- the invention relates to liquid containers used as reagent liquid containers in automatic analyzers.
- reagent liquid is taken from the liquid containers by automatic pipetting. This is done in a faster cycle in more modern systems to allow high throughput of relevant analysis operations.
- the liquid container by means of a transport device, for example in the form of a rotor quickly supplied to the pipetting and braked there, whereupon the automatic pipette or suction needle through the upper opening of the liquid container passes into the extraction chimney to suck liquid.
- a transport device for example in the form of a rotor quickly supplied to the pipetting and braked there, whereupon the automatic pipette or suction needle through the upper opening of the liquid container passes into the extraction chimney to suck liquid.
- each individual pipetting operation including the positioning of the liquid container in the pipetting zone, has extremely short single-second cycle times.
- the pipette tip during pipetting should also dip only slightly into the liquid to be pipetted and the level in the liquid container should be as calm as possible. It should also be avoided that the pipette draws air due to a fluctuating liquid level. Furthermore, foaming in the extraction chimney should be suppressed.
- the state of the art of reaction liquid containers with removal chimney can, for example, on the WO 97/12677 A1 , on the US 5,102,631 or on the DE 38 38 278 C1 to get expelled.
- the tubular discharge chimney is provided at its upper end with a radially outwardly projecting flange, with which it is suspended from a spout of the container opening.
- the completely open lower end of the removal chimney extends into the vicinity of the bottom of the liquid container, so that liquid communication between the removal chimney and the surrounding interior region of the liquid container can only take place via a narrow bottom gap through the lower opening of the removal chimney.
- slit-like wall thickness reductions are provided in the upper region of the extraction chimney, which are intended to allow an influx of air between the mouth of the liquid container and the mantle of the extraction chimney.
- a liquid container with removal chimney is known in which the cross section of the removal chimney is substantially smaller than the cross section of the upper container opening, said removal chimney interspersing a screwed with the mouth grommet screw cap and is fixed on this.
- a through hole in the screw cap allows pressure equalization between the container interior and the external environment.
- the removal chimney extends into the vicinity of the container bottom, so that liquid exchange between the discharge chimney and the surrounding interior of the container can take place through the open underside of the removal chimney.
- the outer circumference of the removal chimney at its upper end and the inner circumference of the discharge chimney surrounding at its upper end spout are only slightly different, so that between the outside of the extraction chimney and the inner surface of the spout not sufficiently large ventilation path for pressure equalization between the container interior and the environment remains.
- a through hole in the jacket of the extraction chimney is provided at its upper end.
- the removal chimney is substantially completely open at its lower end, with spacer webs being provided at the lower end of the withdrawal chimney.
- the from the US 5,102,631 known liquid container is similar to the last-mentioned embodiment of the DE 38 38 278 C1 constructed and thus also has a through hole in the jacket of the discharge chimney at the upper end.
- the extraction chimney extends to the bottom of the liquid container, but large lateral openings are provided in the jacket of the extraction chimney at the lower end.
- the removal chimney According to the operating principle of the removal chimney, it is provided in the known examples that between the lower end of the removal chimney and the opposite container bottom only a small distance and thus only a narrow flow gap to form a large flow resistance is given, so that fluctuations in the container volume outside As far as possible, the discharge chimney can only have a damped effect in the withdrawal chimney.
- the known extraction chimneys thus have at their end adjacent the container bottom end a liquid-permeable zone with a low fluid permeability on.
- the invention has for its object to provide a liquid container of the type mentioned, which can be filled quickly through the upper opening and through the removal chimney and yet in the liquid removal operation, the desired properties of calming the liquid level within the extraction chimney against the fluctuations in the container area outside of the Removal chimney has.
- the removal chimney and thus the liquid-permeable zone can be used e.g. be set so that their fluid permeability is relatively large.
- the liquid-permeable zone can then be set back into a state with low liquid permeability, so that the extraction chimney can fulfill its desired function in liquid removal operation of the liquid container.
- the liquid transmission capacity of the liquid-permeable zone is not completely suppressed in any of the settings of the extraction chimney. In the position of minimum liquid permeability, liquid exchange can thus take place between the removal chimney and the surrounding container body.
- the liquid-permeable zone comprises at least one opening in the lower end region of the extraction chimney whose effective opening cross-section is adjustable, this being done by the rotational movement or the lifting movement of the extraction chimney or a part thereof relative to the liquid container bottom.
- the Ent-nah-mekamin has a pipe section which extends downwardly from the upper container opening and a pipe receptacle provided on the container bottom for the pipe section, whereby the pipe section and the pipe receptacle are inserted into one another. and are adjustable relative to each other to the effective Opening cross-section of the liquid-permeable zone to change.
- the invention include the liquid-permeable zone lateral openings in the pipe section and lateral openings in the pipe receiving in the lower end of the extraction chimney, wherein lateral openings of the pipe section and lateral openings of the pipe receiving relative to each other in common alignment are aligned to the effective opening cross-section of the liquid-permeable zone.
- the change in the transmittance of the liquid-permeable zone simply by the fact that a pipe section of the discharge chimney extending from the upper container opening closer to the container bottom is brought closer to the container bottom, so that only a small flow gap between the container bottom and bottom End of the pipe section remains. This is then the condition of the lower fluid permeability of the liquid-permeable zone.
- the liquid permeability of the liquid-permeable zone is then increased.
- the removal chimney is securely received in the liquid container, so that it is not removable from the latter under normal handling conditions even when the liquid container is open.
- the setting of the removal chimney in the position of greater fluid permeability can be done before the introduction of the liquid container in the automatic filling station or after. What is essential is that the normally automatic and fast filling step occurs while the discharge chimney is set in the position of greater liquid permeability of the liquid-permeable zone.
- the liquid container according to the invention in which the liquid can be filled in a fast-cycling automatic filling station in high-throughput operation to prepare the liquid container for the subsequent provision of the liquid in a high-speed automatic analyzer, wherein the Fluid removal in the automatic analyzer by aspirating fluid from the fluid reservoir by means of a pipette or the like, while the extraction chimney is set in the position of minimum liquid permeability of the liquid-permeable zone. It is thus high-throughput operation in the automatic filling station and high-throughput operation in the automatic analyzer with the liquid container according to the invention possible, without having to accept disadvantages compared to the prior art of the generic liquid container in purchasing.
- the vertical longitudinal section runs centrally through the discharge chimney 3 or 3a.
- the liquid container 1 is a reagent liquid container which is used in the manner described in the beginning in automatic analyzers.
- the liquid container 1 has at its upper end a screw cap opening 5, starting from which a pipe section 7 of the discharge chute 3 extends vertically into the container interior.
- the container bottom 9 has a tube receptacle 11, which has a pot-like shape with two, for example, rectangular, open at the top incisions 13.
- the incisions 13 are in the direction of the Fig. 1a and 1b in flight one behind the other on diametrically opposite sides of the tube receptacles eleventh
- the pipe section 7 is received with its lower end in the pipe receptacle 11, in such a way that it lies with its outer circumference the inner periphery of the pipe receptacle 11 closely adjacent and preferably touching.
- the tube holder 11 thus forms a pivot bearing for the pipe section 7 of the discharge chimney 3, so that the pipe section 7 is rotatable about the vertical axis of rotation 15 between two defined Drehanschlag tooen.
- lateral cuts 17, which are provided at diametrically opposite regions of the pipe section 7 and do not extend beyond the uppermost edge of the pipe receptacle 11 also upward, are rotated relative to the notches 13 of the pipe receiving.
- the cuts 17 and 13 represent lateral openings in the pipe section 7 and in the pipe receptacle 11 and together form a liquid-permeable zone 18 of the discharge chimney 3, whose effective opening cross-section depends on the extent to which the lateral openings 17 of the pipe section 7 in common alignment with the lateral openings 13 of the pipe receiving 11 are.
- Fig. 1a the lateral openings 17 of the pipe section 7 are completely aligned in alignment with the lateral openings 13, so that the openings 13, 17 show a maximum overlap.
- This is the limit position of the maximum effective opening cross-section of the liquid-permeable zone 18 of the discharge chimney 3, ie the defined setting of the larger liquid permeability of the liquid-permeable zone. It can take place in this situation, relatively good fluid exchange between the interior of the discharge chimney 3 and the container volume outside of the discharge chimney 3, which is responsible for filling the Liquid container 1 through the opening 5 and the discharge chimney 3 is important.
- FIG. 1b shows the discharge chimney 3 in the limit of minimum liquid transmittance of the zone 18 with a small effective opening cross-section of the liquid-permeable zone 18, as it is to be selected for the liquid extraction operation.
- Rotary stops which prevent the tube section 7 from being turned beyond the limits shown, are in Fig. 1a and Fig. 1b Not shown.

- the liquid-permeable zone is defined by the annular gap 19, while the discharge chimney pipe section 7a is raised Fig. 2a larger than when lowered extraction chimney pipe section 7a according to Fig. 2b and defined by the crenelated spaces 21.
- Slings 20 and 22 ensure that defined end positions for the stroke adjustment of the pipe section 7a are possible, as this in the Fig. 2a and 2b can be seen.
- Fig. 2a shows a provided for filling the container 1 limit setting of the removal chimney 3a.
- Fig. 2b shows the favorable for the liquid extraction operation limit position of the discharge chimney 3a.
- fluid exchange through zone 18 may occur.
- a variant of the second embodiment with a modification of the lower end of the pipe section 7a is in the Fig. 3a and 3b shown.
- Fig. 3a and 3b has the pipe section 7a at its lower end four spacer webs 22, which ensure that in the lowered state of the pipe section 7a according to Fig. 3b this is not occlusive with its lower edge on the bottom 9 and also on the circumference of the circumference circumferential collar 24th maintains a distance to the vessel bottom 9, so that the liquid-permeable zone 18 in Fig. 3b With reduced fluid permeability, fluid communication between the interior of the withdrawal chimney 3a and the container volume outside the withdrawal chimney can take place.
- Fig. 3a shows a provided for filling the container 1 setting the removal chimney 3a.

Description
Die Erfindung betrifft einen Flüssigkeitsbehälter mit einer oberen Öffnung und mit einem in Flucht mit der oberen Öffnung in den Behälter hineinreichenden, rohrartigen Entnahmekamin für Flüssigkeitsentnahme mittels eines von oben in den Entnahmekamin einzubringenden Entnahmeelementes, insbesondere einer Pipette, wobei der Entnahmekamin in seinem unteren, dem Behälterboden benachbarten Endbereich eine flüssigkeitsdurchlässige Zone aufweist.The invention relates to a liquid container having an upper opening and extending into alignment with the upper opening into the container, tubular removal chute for liquid removal by means of a to be introduced from above into the extraction chimney extraction element, in particular a pipette, wherein the removal chimney in its lower, the container bottom adjacent end region has a liquid-permeable zone.
Die Erfindung bezieht sich insbesondere auf Flüssigkeitsbehälter, die als Reagenzflüssigkeitsgefäße in automatischen Analysegeräten verwendet werden. Bei dem Einsatz in einem solchen automatischen Analysegerät wird den Flüssigkeitsbehältern Reagenzflüssigkeit durch automatisches Pipettieren entnommen. Dies erfolgt bei moderneren Systemen in einem schnellen Takt, um einen hohen Durchsatz an betreffenden Analysevorgängen zu ermöglichen. Dabei werden die Flüssigkeitsbehälter mittels einer Transportvorrichtung z.B. in Gestalt eines Rotors rasch der Pipettierstation zugeführt und dort abgebremst, woraufhin die automatische Pipette oder Saugnadel durch die obere Öffnung des Flüssigkeitsbehälters hindurch in den Entnahmekamin eintaucht, um Flüssigkeit abzusaugen. Bei automatischen Analysegeräten für einen hohen Durchsatz stehen für jeden einzelnen Pipettiervorgang einschließlich des Positionierens des Flüssigkeitsbehälters in der Pipettierzone nur äußerst kurze Zykluszeiten von einzelnen Sekunden zur Verfügung. Dabei tritt das Problem auf, dass beim abrupten Abstoppen des Flüssigkeitsbehälters in der Pipettierzone die Flüssigkeit im Behälter schwappt und ggf. aufspritzt, so dass sich ein einigermaßen ausgeglichener Flüssigkeitspegel oft erst nach einer jeweiligen Wartezeit einstellt, die länger dauert, als die geforderte kurze Pipettierzykluszeit für den Hochdurchsatzbetrieb. Das Pipettieren bei noch stark schwankendem Flüssigkeitspegel in dem Entnahmekamin soll üblicherweise vermieden werden, da hierbei die Pipettenspitze außen über einen relativ großen Bereich in unerwünschter Weise mit der Flüssigkeit benetzt wird und so ein vergleichsweise großes Mitreißvolumen an Flüssigkeit beim Zurückziehen der Pipette aus dem Flüssigkeitsbehälter außen an der Pipettenspitze hängen bleibt und dann bei weiteren Pipettiervorgängen Kontaminierungen verursacht. Um dies zu vermeiden, sollte die Pipettenspitze beim Pipettieren auch nur wenig in die zu pipettierende Flüssigkeit eintauchen und der Füllstand in dem Flüssigkeitsbehälter möglichst in Ruhe sein. Auch soll vermieden werden, dass die Pipette aufgrund eines schwankenden Flüssigkeitspegels Luft zieht. Ferner sollte Schaumbildung im Entnahmekamin unterdrückt sein.More particularly, the invention relates to liquid containers used as reagent liquid containers in automatic analyzers. When used in such an automatic analyzer, reagent liquid is taken from the liquid containers by automatic pipetting. This is done in a faster cycle in more modern systems to allow high throughput of relevant analysis operations. The liquid container by means of a transport device, for example in the form of a rotor quickly supplied to the pipetting and braked there, whereupon the automatic pipette or suction needle through the upper opening of the liquid container passes into the extraction chimney to suck liquid. With high throughput automated analyzers, each individual pipetting operation, including the positioning of the liquid container in the pipetting zone, has extremely short single-second cycle times. The problem arises that during the abrupt stopping of the liquid container in the pipetting zone, the liquid in the container sloshes and possibly splashes, so that a fairly balanced liquid level often sets only after a respective waiting time that lasts longer than the required short pipetting cycle time for the high-throughput operation. The pipetting with still strongly fluctuating liquid level in The extraction chimney should usually be avoided, since in this case the pipette tip is undesirably wetted with the liquid over a relatively large area and thus a comparatively large entrainment volume of liquid adheres to the pipette tip when the pipette is withdrawn from the liquid container and then at further Pipetting causes contamination. In order to avoid this, the pipette tip during pipetting should also dip only slightly into the liquid to be pipetted and the level in the liquid container should be as calm as possible. It should also be avoided that the pipette draws air due to a fluctuating liquid level. Furthermore, foaming in the extraction chimney should be suppressed.
Zum Stand der Technik von Reaktionsflüssigkeitsbehältern mit Entnahmekamin kann z.B. auf die
Aus der
Der aus der
Dem Funktionsprinzip des Entnahmekamins entsprechend, ist es bei den bekannten Beispielen vorgesehen, dass zwischen dem unteren Ende des Entnahmekamins und dem gegenüberliegenden Behälterboden nur ein kleiner Abstand und somit nur ein schmaler Strömungsspalt zur Bildung eines großen Strömungswiderstandes gegeben ist, so dass sich Schwankungen im Behältervolumen außerhalb des Entnahmekamins möglichst nur gedämpft im Entnahmekamin auswirken können. Die bekannten Entnahmekamine weisen somit an ihren dem Behälterboden benachbarten Endbereich eine flüssigkeitsdurchlässige Zone mit einem geringen Flüssigkeitsdurchlassvermögen auf.According to the operating principle of the removal chimney, it is provided in the known examples that between the lower end of the removal chimney and the opposite container bottom only a small distance and thus only a narrow flow gap to form a large flow resistance is given, so that fluctuations in the container volume outside As far as possible, the discharge chimney can only have a damped effect in the withdrawal chimney. The known extraction chimneys thus have at their end adjacent the container bottom end a liquid-permeable zone with a low fluid permeability on.
Diese für die gewünschte Funktion des Entnahmekamins an sich notwendige Begrenzung des Flüssigkeitsdurchlassvermögens bringt jedoch auch Nachteile mit sich, nämlich bei solchen Flüssigkeitsbehältern der hier betrachteten Art, die durch den Entnahmekamin hindurch von der oberen Öffnung her zunächst mit Flüssigkeit zu füllen sind. Das Befüllen muß sehr langsam erfolgen, da der Füllstand im Entnahmekamin aufgrund des geringen Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone sehr viel schneller ansteigt als der Füllstand in dem Behälterbereich außerhalb des Entnahmekamins. Bei zu schnellem Befüllen kann es zum Überlaufen der Flüssigkeit an der oberen Öffnung des Behälters kommen.However, this necessary for the desired function of the withdrawal chimney per se limitation of the liquid transmittance also brings disadvantages, namely in such liquid containers of the type considered here, which are to be filled by the discharge chimney from the upper opening forth first with liquid. The filling must be very slow, since the level in the discharge chimney, due to the low fluid permeability of the liquid-permeable zone increases much faster than the level in the container area outside the discharge chimney. Overfilling may cause overflow of liquid at the top of the container.
Auch bei konventionellen Flüssigkeitsbehältern, bei denen der Entnahmekamin erst nach dem Befüllen einzusetzen ist, zeigte sich das Problem, dass ein Überlaufen von Flüssigkeit durch die obere Behälteröffnung nur vermieden werden kann, wenn der Entnahmekamin vergleichsweise langsam in den Behälter eingeführt wird, da aufgrund des geringen Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone am unteren Kaminende die Flüssigkeit nicht schnell genug in den Kamin hochsteigen kann.Even with conventional liquid containers in which the removal chimney is to be used only after filling, there was the problem that overflow of liquid through the upper container opening can only be avoided if the discharge chimney is introduced comparatively slowly into the container, since due to the low Liquid permeability of the liquid-permeable zone at the bottom of the chimney end, the liquid can not rise quickly enough in the chimney.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, einen Flüssigkeitsbehälter der eingangs genannten Art bereitzustellen, der bedarfsweise schnell durch die obere Öffnung und durch den Entnahmekamin hindurch befüllbar ist und dennoch im Flüssigkeitsentnahmebetrieb die gewünschten Eigenschaften der Beruhigung des Flüssigkeitspegels innerhalb des Entnahmekamins gegenüber den Schwankungen im Behälterbereich außerhalb des Entnahmekamins aufweist.The invention has for its object to provide a liquid container of the type mentioned, which can be filled quickly through the upper opening and through the removal chimney and yet in the liquid removal operation, the desired properties of calming the liquid level within the extraction chimney against the fluctuations in the container area outside of the Removal chimney has.
Zur Lösung dieser Aufgabe wird in einem Aspekt ausgehend von einem Flüssigkeitsbehälter der eingangs genannten Art erfindungsgemäß vorgeschlagen, den Flüssigkeitsbehälter weitergehend entsprechend der Merkmale des kennzeichnenden Teils des Anspruchs 1 auszubilden. Zur Lösung dieser Aufgabe wird in einem weiteren Aspekt ausgehend von einem Flüssigkeitsbehälter der eingangs genannten Art erfindungsgemäß vorgeschlagen, den Flüssigkeitsbehälter weitergehend entsprechend der Merkmale des kennzeichnenden Teils des Anspruchs 2 auszubilden.To solve this problem is in one aspect, starting from a Liquid container of the type mentioned according to the invention proposed further form the liquid container according to the features of the characterizing part of claim 1. To solve this problem is proposed according to the invention in a further aspect, starting from a liquid container of the type mentioned, further form the liquid container according to the features of the characterizing part of claim 2.
Für einen Befüllvorgang des Flüssigkeitsbehälters kann der Entnahmekamin und somit die flüssigkeitsdurchlässige Zone z.B. so eingestellt werden, dass ihr Flüssigkeitsdurchlassvermögen relativ groß ist. Nach dem Befüllvorgang kann dann die flüssigkeitsdurchlässige Zone wieder in einen Zustand mit geringem Flüssigkeitsdurchlassvermögen zurückversetzt werden, so dass der Entnahmekamin seine gewünschte Funktion im Flüssigkeitsent-nahme-be-trieb des Flüssigkeitsbehälters erfüllen kann. Insbesondere ist das Flüs-sigkeitsdurchlassvermögen der flüssigkeitsdurchlässigen Zone in keiner der Einstellungen des Entnahmekamins vollständig unterdrückt. In der Stellung minimalen Flüssigkeitsdurchlassvermögens kann somit Flüssigkeitsaus-tausch zwischen dem Entnahmekamin und dem ihn umgebenden Behäl-terkörper stattfinden.For a filling operation of the liquid container, the removal chimney and thus the liquid-permeable zone can be used e.g. be set so that their fluid permeability is relatively large. After the filling process, the liquid-permeable zone can then be set back into a state with low liquid permeability, so that the extraction chimney can fulfill its desired function in liquid removal operation of the liquid container. In particular, the liquid transmission capacity of the liquid-permeable zone is not completely suppressed in any of the settings of the extraction chimney. In the position of minimum liquid permeability, liquid exchange can thus take place between the removal chimney and the surrounding container body.
Vorzugsweise umfasst die flüssigkeitsdurchlässige Zone wenigstens eine Öffnung in dem unteren Endbereich des Entnahmekamins, deren effektiver Öffnungsquerschnitt einstellbar ist, wobei dies durch die Drehbewegung bzw. die Hubbewegung des Entnahmekamins oder eines Teils desselben relativ zum Flüssigkeitsbehälterboden erfolgt.Preferably, the liquid-permeable zone comprises at least one opening in the lower end region of the extraction chimney whose effective opening cross-section is adjustable, this being done by the rotational movement or the lifting movement of the extraction chimney or a part thereof relative to the liquid container bottom.
Gemäß dem ersten Aspekt der Erfindung hat der Ent-nah-mekamin einen sich von der oberen Behälteröffnung nach unten er-stre-cken-den Rohrabschnitt und eine am Behälterboden vorgesehene Rohr-aufnahme für den Rohrabschnitt, wobei der Rohrabschnitt und die Rohraufnahme ineinander gesteckt - und relativ zueinander einstellbar sind, um den effektiven Öffnungsquerschnitt der flüssigkeitsdurchlässigen Zone zu verändern. Bei einer solchen Ausführungsform der Erfindung gehören zu der flüssigkeitsdurchlässigen Zone seitliche Öffnungen in dem Rohrabschnitt und seitliche Öffnungen in der Rohraufnahme im unteren Endbereich des Entnahmekamins, wobei seitliche Öffnungen des Rohrabschnittes und seitliche Öffnungen der Rohraufnahme relativ zueinander in gemeinsamer Flucht ausrichtbar sind, um den effektiven Öffnungsquerschnitt der flüssigkeitsdurchlässigen Zone zu vergrößern.According to the first aspect of the invention the Ent-nah-mekamin has a pipe section which extends downwardly from the upper container opening and a pipe receptacle provided on the container bottom for the pipe section, whereby the pipe section and the pipe receptacle are inserted into one another. and are adjustable relative to each other to the effective Opening cross-section of the liquid-permeable zone to change. In such an embodiment of the invention include the liquid-permeable zone lateral openings in the pipe section and lateral openings in the pipe receiving in the lower end of the extraction chimney, wherein lateral openings of the pipe section and lateral openings of the pipe receiving relative to each other in common alignment are aligned to the effective opening cross-section of the liquid-permeable zone.
Alternativ erfolgt gemäß dem zweiten Aspekt der Erfindung die Veränderung des Durchlassvermögens der flüssigkeitsdurchlässigen Zone einfach dadurch, dass ein sich von der oberen Behälteröffnung nahe zum Behälterboden erstreckender Rohrabschnitt des Entnahmekamins näher an den Behälterboden herangeführt wird, so dass nur noch ein kleiner Durchflussspalt zwischen Behälterboden und unterem Ende des Rohrabschnittes verbleibt. Dies ist dann der Zustand des geringeren Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone. Durch Anheben des Rohrabschnittes und dem damit einhergehenden Vergrößern des Abstandes zwischen dem unteren Ende des Rohrabschnittes und dem Behälterboden wird dann das Flüssigkeitsdurchlassvermögen der flüssigkeitsdurchlässigen Zone vergrößert.Alternatively, according to the second aspect of the invention, the change in the transmittance of the liquid-permeable zone simply by the fact that a pipe section of the discharge chimney extending from the upper container opening closer to the container bottom is brought closer to the container bottom, so that only a small flow gap between the container bottom and bottom End of the pipe section remains. This is then the condition of the lower fluid permeability of the liquid-permeable zone. By raising the pipe section and thus increasing the distance between the lower end of the pipe section and the container bottom, the liquid permeability of the liquid-permeable zone is then increased.
Vorzugsweise ist der Entnahmekamin in dem Flüssigkeitsbehälter gesichert aufgenommen, so dass er unter normalen Handhabungsbedingungen auch bei geöffnetem Flüssigkeitsbehälter nicht aus letzterem herausnehmbar ist.Preferably, the removal chimney is securely received in the liquid container, so that it is not removable from the latter under normal handling conditions even when the liquid container is open.
Gegenstand der Erfindung ist ferner ein Verfahren zur Präparierung eines Flüssigkeitsbehälters nach einem der vorhergehenden Ansprüche für die Bereitstellung einer Flüssigkeit in einem automatischen Analysegerät, umfassend die Schritte:
- Bereitstellen des Flüssigkeitsbehälters in einer automatischen Füllstation,
- Sicherstellen, dass für einen folgenden Einfüllschritt der Entnahmekamin in dem Flüssigkeitsbehälter in der Stellung größeren Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone eingestellt ist,
- Einfüllen der Flüssigkeit durch den Entnahmekamin hindurch in den Flüssigkeitsbehälter, während der Entnahmekamin in der Stellung größeren Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone eingestellt ist,
- Verschließen des Flüssigkeitsbehälters,
- Einstellen des Entnahmekamins in die Stellung minimalen Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone als Vorbereitungsschritt für die Entnahme von Flüssigkeit aus dem Behälter.
- Providing the liquid container in an automatic filling station,
- Make sure that for a subsequent filling step the extraction chimney in the liquid container is set in the position of larger liquid permeability of the liquid-permeable zone,
- Filling the liquid through the extraction chimney into the liquid container while the extraction chimney is set in the position of larger liquid permeability of the liquid-permeable zone,
- Closing the liquid container,
- Adjusting the discharge chimney in the position of minimum liquid permeability of the liquid-permeable zone as a preparation step for the removal of liquid from the container.
Die Einstellung des Entnahmekamins in die Stellung größeren Flüssigkeitsdurchlassvermögens kann vor dem Einbringen des Flüssigkeitsbehälters in die automatische Füllstation oder danach erfolgen. Wesentlich ist, dass der normalerweise automatische und schnell durchgeführte Schritt des Einfüllens erfolgt, während der Entnahmekamin in der Stellung größeren Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone eingestellt ist.The setting of the removal chimney in the position of greater fluid permeability can be done before the introduction of the liquid container in the automatic filling station or after. What is essential is that the normally automatic and fast filling step occurs while the discharge chimney is set in the position of greater liquid permeability of the liquid-permeable zone.
Das Einstellen des Entnahmekamins in die Stellung minimalen Flüssigkeitsdurchlassvermögens erfolgt nach dem Befüllen, wobei dieser Vorbereitungsschritt für die Entnahme von Flüssigkeit aus dem Behälter vor dem Verschließen des Flüssigkeitsbehälters oder danach und ggf. erst an einem anderen Ort, etwa in einem automatischen Analysegerät, erfolgen kann.The setting of the removal chimney in the position of minimum liquid permeability occurs after filling, this preparation step for the removal of liquid from the container prior to closing the liquid container or thereafter and possibly only in another place, such as in an automatic analyzer, can take place.
Es wird somit eine besonders vorteilhafte Verwendung des Flüssigkeitsbehälters nach der Erfindung vorgeschlagen, bei der die Flüssigkeit in einer schnell getakteten automatischen Füllstation im Hochdurchsatzbetrieb eingefüllt werden kann, um den Flüssigkeitsbehälter für die spätere Bereitstellung der Flüssigkeit in einem schnell getakteten automatischen Analysegerät zu präparieren, wobei die Flüssigkeitsentnahme in dem automatischen Analysegerät durch Absaugen von Flüssigkeit aus dem Flüssigkeitsbehälter mittels einer Pipette oder dgl. erfolgt, während der Entnahmekamin in der Stellung minimalen Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone eingestellt ist. Es ist somit Hochdurchsatzbetrieb in der automatischen Füllstation und Hochdurchsatzbetrieb im automatischen Analysegerät mit dem Flüssigkeitsbehälter nach der Erfindung möglich, ohne Nachteile gegenüber dem Stand der Technik der gattungsgemäßen Flüssigkeitsbehälter in Kauf nehmen zu müssen.It is thus proposed a particularly advantageous use of the liquid container according to the invention, in which the liquid can be filled in a fast-cycling automatic filling station in high-throughput operation to prepare the liquid container for the subsequent provision of the liquid in a high-speed automatic analyzer, wherein the Fluid removal in the automatic analyzer by aspirating fluid from the fluid reservoir by means of a pipette or the like, while the extraction chimney is set in the position of minimum liquid permeability of the liquid-permeable zone. It is thus high-throughput operation in the automatic filling station and high-throughput operation in the automatic analyzer with the liquid container according to the invention possible, without having to accept disadvantages compared to the prior art of the generic liquid container in purchasing.

In den Figuren verläuft der vertikale Längsschnitt mittig durch den Entnahmekamin 3 bzw. 3a.In the figures, the vertical longitudinal section runs centrally through the
Bei dem Flüssigkeitsbehälter 1 handelt es sich um ein Reagenzflüssigkeitsgefäß, das in der eingangs beschriebenen Weise in automatischen Analysegeräten verwendet wird.The liquid container 1 is a reagent liquid container which is used in the manner described in the beginning in automatic analyzers.
Der Flüssigkeitsbehälter 1 weist an seinem oberen Ende eine Schraubverschlußöffnung 5 auf, von der ausgehend ein Rohrabschnitt 7 des Entnahmekamins 3 vertikal in das Behälterinnere hinein reicht. Der Behälterboden 9 weist eine Rohraufnahme 11 auf, welche eine topfartige Form mit zwei beispielsweise rechteckigen, nach oben hin offenen Einschnitten 13 hat. Die Einschnitte 13 liegen in Betrachtungsrichtung der
Der Rohrabschnitt 7 ist mit seinem unteren Ende in der Rohraufnahme 11 aufgenommen, und zwar so, dass er mit seinem Außenumfang dem Innenumfang der Rohraufnahme 11 eng benachbart und vorzugsweise berührend gegenüber liegt. Die Rohraufnahme 11 bildet somit ein Drehlager für den Rohrabschnitt 7 des Entnahmekamins 3, so dass der Rohrabschnitt 7 um die vertikale Drehachse 15 zwischen zwei definierten Drehanschlagstellungen drehbar ist. Dabei können seitliche Einschnitte 17, die an diametral gegenüberliegenden Bereichen des Rohrabschnitts 7 vorgesehen sind und nicht über den obersten Rand der Rohraufnahme 11 hinaus nach oben reichen, relativ zu den Einschnitten 13 der Rohraufnahme verdreht werden. Die Einschnitte 17 und 13 stellen seitliche Öffnungen in dem Rohrabschnitt 7 und in der Rohraufnahme 11 dar und bilden gemeinsam eine flüssigkeitsdurchlässige Zone 18 des Entnahmekamins 3, deren wirksamer Öffnungsquerschnitt davon abhängt, inwieweit die seitlichen Öffnungen 17 des Rohrabschnittes 7 in gemeinsamer Flucht mit den seitlichen Öffnungen 13 der Rohraufnahme 11 liegen. In
Für einen späteren Flüssigkeitsentnahmebetrieb, bei dem Flüssigkeit mittels einer Pipette oder Saugnadel von oben aus dem Entnahmekamin 3 abgesaugt werden soll, ist eine gute Flüssigkeitskommunikation zwischen dem Inneren des Entnahmekamins und dem Behältervolumen außerhalb des Entnahmekamins sehr ungünstig, da sich Schwankungen der Flüssigkeit im Behältervolumen außerhalb des Entnahmekamins 3 rasch und nur wenig gedämpft auf das Innere des Entnahmekamins 3 übertragen. Dieses Problem wird mit dem Flüssigkeitsbehälter gemäß
Es sei darauf hingewiesen, dass in den Figuren Belüftungskanäle oder Abstandsbuchten zwischen der Innenfläche 6 der Schraubverschlusstülle und dem Außenumfang des Rohrabschnittes 7 oder Belüftungsöffnungen im oberen Bereich des Rohrabschnittes 7, die für einen Druckausgleich zwischen der Außenumgebung und dem Behälterinneren sorgen, nicht eingezeichnet sind. Solche oberen Belüftungsmaßnahmen sind in der Praxis erfindungsgemäß jedoch vorgesehen. Hierzu kann auf verschiedenste Vorschläge aus dem Stand der Technik zurückgegriffen werden. Dies gilt auch für das zweite Ausführungsbeispiel gemäß den
Bei der Darstellung des zweiten Ausführungsbeispiels in den
Bei dem zweiten Ausführungsbeispiel erfolgt das Variieren des Flüssigkeitsdurchlassvermögens der flüssigkeitsdurchlässigen Zone 18 durch eine Hubbewegung des Rohrabschnittes 7a relativ zu dem Gefäßboden 9. Die flüssigkeitsdurchlässige Zone ist durch den Ringspalt 19, der bei angehobenem Entnahmekamin-Rohrabschnitt 7a gemäß
Eine Variante des zweiten Ausführungsbeispiels mit einer Abänderung des unteren Endes des Rohrabschnittes 7a ist in den
Bei der Ausführungsform nach den
Es sind zahlreiche Abwandlungen der beschriebenen Ausführungsbeispiele denkbar. So kann der Entnahmekamin z.B. durch eine kombinierte Hub- und Drehbewegung verstellbar sein. Dies kann insbesondere eine Schraubbewegung des Entnahmekamins sein.Numerous modifications of the described embodiments are conceivable. Thus, the extraction chimney can e.g. be adjustable by a combined lifting and turning movement. This may in particular be a screwing movement of the removal chimney.
Der Entnahmekamin kann insbesondere bereits vor der Abfüllung des Flüssigkeitsbehälters darin montiert sein.The extraction chimney can in particular already be mounted therein before the filling of the liquid container.
