Abstract
The invention relates to a liquid transfer consumable, and discloses an elongated conductive disposable sample adding tip. The elongated conductive disposable sample adding tip is characterized by comprising an integrally approximately conical sample adding tube, wherein the interior of the sample adding tube is a communicated cavity; and the sample adding tube comprises an end part combined with sample adding equipment, an elongated conical tip part and a middle part for connecting the end part and the tip part. The elongated conductive disposable sample adding tip has good conductivity, deformation, rigidity, finishment, smooth surface, pointed nozzle, thick wall and small smooth caliber, and ensures that the volume of the distributed trace liquid specimen is infinitely close to the theoretical volume; and the length of the slope structure of the tip part is increased and the mirror surface of the inner wall is smooth and effective, so that stringing in the sample adding process is effectively reduced, and the sample adding precision is improved.
Description
Technical field
The present invention relates to a kind of liquid consumptive material that moves, relate in particular to a kind of disposable application of sample point.
Background technology
The alternative permanent sample needle of disposable application of sample point that conducts electricity is used for distribution and the transfer to various liquid, use disposable application of sample point convenient, clean, the traction of can avoiding intersecting pollutes, realization is to the distribution of micro-sample, clinical examination, pharmacy, life science, animals and plants inspection and quarantine research etc. have been widely used in, be usually used in handling the application of sample work of test of serology ELISA Plate and blood group experiment clinically, as blood station, hospital, public security system, Molecular Biology Lab etc.The liquid-transfering gun head and the disposable application of sample point corresponding matching that typically use in the sample charging mechanism of full-automatic loading device are used, and sample is taken a sample or the distribution of application of sample.Because of disposable application of sample point is distribution and transfer to micro-sample, its structure and application of sample quality are closely related, therefore disposable application of sample point structure is also improved in constantly exploring, and combines closely with loading device to guarantee the application of sample point better, prevents the generation of the phenomenon of leakage; The sample volume that guarantees to distribute reduces the extension pearl phenomenon in the application of sample process infinitely near theoretical volume, satisfies the requirement of application of sample precision etc.
Summary of the invention
Technical matters to be solved by this invention provides a kind of extended type and conducts electricity disposable application of sample point, and the micro liquid sample volume that guarantees to distribute reduces the extension pearl phenomenon in the application of sample process infinitely near theoretical volume, improves application of sample precision.
For solving the problems of the technologies described above, the invention provides a kind of extended type and conduct electricity disposable application of sample point, it is characterized in that, comprise the approximate conical application of sample pipe of a whole one-tenth, described application of sample pipe inside is a cavity that is communicated with, it is characterized in that described application of sample pipe comprises the end that can combine with loading device, the conical tip of a lengthening, connect the middle part of described end and described tip.
The internal chamber wall upper edge circumference at described middle part is provided with the annulus to the chamber internal projection.
Described annulus is interval with 2 circles vertically.
Described annulus to the chamber internal projection is circular-arc at high spot.
Described annulus is located at the place, close described end at described middle part.
The port of described end inner chamber is provided with shoulder.
Be uniformly distributed with the reinforcement rib along the circumference on the outer wall of described end.
Diameter with circular cone dwindles gradually, and the outer wall thickness of described tip reduces gradually, forms a not only thin but also long conical tip, and is littler to the sharp-crested place bore of circular cone tip, wall is thinner, inner chamber is littler.
The beneficial effect that the present invention reached: extended type of the present invention conducts electricity disposable application of sample point, has good electrical conductivity, deformation behavior, rigidity, smooth finish, smooth surface, sharp mouth wall approach, smooth bore is little, the micro liquid sample volume that guarantees to distribute is infinitely near theoretical volume, tip ramp structure length lengthening, inwall mirror-smooth effectively reduce the extension pearl phenomenon in the application of sample process, thereby have improved application of sample precision.
Description of drawings

Fig. 2 is the longitudinal sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1 and Figure 2, a kind of extended type conducts electricity disposable application of sample point and comprises that one whole becomes approximate conical application of sample pipe 1, application of sample pipe 1 inside is a cavity 2 that is communicated with, and the application of sample pipe comprises the middle part 5 of conical tip 4, connection end 3 and the tip 4 of end 3, a lengthening.
The internal chamber wall upper edge circumference at middle part 5 is provided with the annulus 51 to the chamber internal projection.Annulus 51 to the chamber internal projection is circular-arc 52 at high spot.Annulus 51 is interval with 2 circles vertically.Annulus 51 is located on the middle part 5 near 3 places, end.
The port of end 3 inner chambers is provided with shoulder 31, seals when being convenient to be connected with loading device.Be uniformly distributed with along the circumference on 3 outer walls of end and strengthen rib 32.
Diameter with circular cone dwindles gradually, the outer wall thickness of tip reduces gradually, the conical tip that the pointed one-tenth of the disposable application of sample of general conduction one is not only thin but also long, ramp structure length lengthening in tip is littler to the sharp-crested place bore of conical tip, wall is thinner, inner chamber is littler.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
