Description
Technical field
The invention belongs to chemistry, technical field of chemical, relate to the laboratory and adopt liquid device, especially for the quantitative liquid taking device of volatile liquid under comparatively airtight condition.
Background technology
Volatile liquid (as acid anhydrides in volatile hydrochloric acid, ammoniacal liquor, hydrogen sulfide solution and the organic matter in the inorganic matter etc.) is the liquid commonly used of chemical experiment, the present liquid mode of getting is to measure with graduated cylinder and pipette after opening bottle cap, get in this way in the liquid process, a large amount of escaping gases overflows from former bottle and graduated cylinder in a large number, volatile liquid often has excitant, and the person's that adopts liquid eyes, nose and throat caused great injury.Volatile liquid often has water imbibition, and after the reagent suction, quality descends, and concentration is inaccurate, and is that have even unrenewable, causes the significant wastage of reagent.Part student is in getting the liquid process, and it is too much to get liquid, and the liquid of getting can not be refunded former bottle in accordance with regulations, and the liquid of getting is forced to pour into tank more, so, not only wastes reagent, and even more serious is to pollute environment.At present, do not have the airtight liquid systems of adopting of ready-made volatile liquid, in order to ensure the quality safety of breadboard with fresh air, experiment student's physical and mental health and chemical experiment reagent, research and development and adopt volatile liquid airtight to adopt liquid systems very necessary.
Summary of the invention
Be to solve problem of environment pollution caused in the volatile liquid gatherer process, the purpose of this invention is to provide a kind of quantitative liquid taking device under airtight condition comparatively, reduce the gasification of getting volatile liquid in the liquid process as far as possible, overflow.
Present design is as follows:
The liquid storage bottle (2) of placing volatile liquid links to each other with the import of scale separatory funnel (4) by a drainage tube, the entrance point of scale separatory funnel (4) seals with cork, drainage tube passes cork and enters scale separatory funnel (4), on cork, insert a breather pipe, the opening of breather pipe uses sealing shroud (5), drainage tube and breather pipe have a piston respectively, the port of export at scale separatory funnel (4) has a piston, there is a sealing shroud (6) in the exit, the bottleneck of liquid storage bottle (2) seals with cork, insert a pressure breathing pipe (1) on the cork, an airtight folder (3) and sealing shroud (7) are arranged on the pressure breathing pipe (1), and the riding position of liquid storage bottle (2) is higher than scale separatory funnel (4).Also can adopt buret to substitute above-mentioned scale separatory funnel (4).
The method that liquid storage bottle (2) adopts bottleneck to make progress is settled.
Description of drawings
The method that Fig. 1 makes progress for the employing bottleneck is settled the volatile liquid quantitative liquid taking device overall structure schematic diagram of liquid storage bottle.
The specific embodiment
Embodiment:
As shown in Figure 1, liquid storage bottle (2) height places on scale separatory funnel (4) or the buret, places with the method that bottleneck makes progress.Get the forward and backward piston of liquid and disconnect, airtight folder (3) closes, and upper sleeve gasket is all overlapped in all openings, exit.
In the time of need getting liquid, take off sealing shroud (7), open airtight folder (3), squeezing into air from pressure breathing pipe (1) pressurizes in liquid storage bottle (2), volatile liquid enters drainage tube under pressure, after treating that drainage tube is filled with liquid, stop pressurization, change two pistons of logical scale separatory funnel (4) upper end drainage tube and breather pipe, take off sealing shroud (5), liquid flows in the scale separatory funnel (4), after flowing sufficient aequum, close the piston of drainage tube, open sealing shroud (6), change the piston of logical scale separatory funnel (4) lower end, pick out liquid.
Close all pistons on clips (3) and the scale separatory funnel (4), put all sealing shrouds.
The bottleneck of liquid storage bottle in the above-mentioned example (2) seals with sillicon rubber blocking, and the connecting duct of device also uses silicon rubber, is not subjected to the pollution of connecting duct with material to ensure the reagent of being got.
This apparatus features is almost can quantitatively get required liquid under the full closeding state, suit to use, can ensure the quality safety of breadboard with fresh air, experiment student's physical and mental health and chemical experiment reagent to large extent at chemistry, chemical industry, medical science, agronomy, Chemistry Laboratory in Middle School and environment-friendly laboratory.
The quantitative liquid getting system of the design's volatile liquid is succinct, practical, gets liquid convenience, safety.Can in the original reagent bottle, use sillicon rubber blocking instead by bottle stopper, insert not liquid sucking tube with reagent reacting, adopt pressurization back liquid spontaneous current flowing mode to get liquid, liquid enters in the scale buret of scale separatory funnel or repacking quantitatively, and get liquid the person can take out quantitative volatile liquid easily from the scale buret of scale separatory funnel or repacking.
Claims (3)
1. volatile liquid quantitative liquid taking device, it is characterized in that: liquid storage bottle (2) links to each other with the import of scale separatory funnel (4) by a drainage tube, the entrance point of scale separatory funnel (4) seals with cork, drainage tube passes cork and enters scale separatory funnel (4), on cork, insert a breather pipe, the opening of breather pipe uses sealing shroud (5), drainage tube and breather pipe have a piston respectively, the port of export at scale separatory funnel (4) has a piston, there is a sealing shroud (6) in the exit, the bottleneck of liquid storage bottle (2) seals with cork, insert a pressure breathing pipe (1) on the cork, an airtight folder (3) and sealing shroud (7) are arranged on the pressure breathing pipe (1), and the riding position of liquid storage bottle (2) is higher than scale separatory funnel (4).
