Abstract
Pipette tips are appliances normally used for sampling in biochemical laboratories. The utility model relates to a novel pipette tip, which is characterized in that an inner cavity and a connector are separated by means of a perforated partition arranged in the inner cavity at the joint of the tip with a pipette. Accordingly, liquid inside the tip can be effectively prevented from adhering to the pipette, cross contamination is reduced, and all functions of the original tip are maintained.
Description
Technical field
The consumptive material of using always when the pipettor suction nozzle is Biochemical Lab's sampling.The utility model relates to a kind of novel pipettor suction nozzle, can reduce the cross pollution that pipettes in the liquid process effectively.
Background technology
At present, the pipettor suction nozzle that sell in market mainly is the tubular article of the hollow processed with polythene material, is used to be installed in pipettor, and the air pressure that relies on pipettor to produce sucks and the liquid that spues.According to the pipettor model, promptly pipette the liquid maximum volume at every turn, used suction nozzle varies in size, and common have several specifications such as 50000 microlitres, 1000 microlitres, 200 microlitres, 10 microlitres.But the inner chamber of existing its carrying liquid of suction nozzle directly contacts with pipettor, so the interior liquid of suction nozzle is easy to stick on the pipettor in actual use, thereby changes the new suction nozzle of suction nozzle after stain, causes the cross pollution of sampling next time.Particularly during the pipettor horizontal, debris refluxes, and pollutes more easily.
Summary of the invention
Form the deficiency that adheres to pollution easily for overcoming existing suction nozzle, the utility model provides a kind of suction nozzle, and this suction nozzle can prevent effectively that liquid adheres on the pipettor in the suction nozzle, avoids cross pollution, and keeps the repertoire of original suction nozzle.
The utility model solves the technical scheme that its technical problem adopted: a kind of pipettor suction nozzle, at suction nozzle afterbody inner chamber the partition body of a perforate is set, and the cavity of contain fluid is separated (interface docks with pipettor) with suction nozzle afterbody interface.Based on such structure, both made pipettor is kept flat, the debris in the chamber can not flow backwards yet, and touches pipettor, and the partition of center drilling guarantees that pipettor produces air pressure in suction nozzle simultaneously, and is identical with existing suction nozzle function.
The described pipettor suction nozzle of the utility model, said partition body is preferably placed near suction nozzle and pipettor contact site.
The described pipettor suction nozzle of the utility model, said perforate are preferably placed at and cut off the body center.
The described pipettor suction nozzle of the utility model, the shape of said perforate can be circle, hexagon, rectangle, square.
The described pipettor suction nozzle of the utility model, the area of said perforate preferably account for and cut off body 1/3rd.
The described pipettor suction nozzle of the utility model, the said partition body preferably material with suction nozzle is identical.
The described pipettor suction nozzle of the utility model, the material of said suction nozzle can be plastics or glass.
The beneficial effect of the utility model is, do not influencing under the actual effect prerequisite of liquid-transfering sucker, and cavity and interface are separated, and avoids cross pollution.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing 1 is the generalized section of the utility model.
The specific embodiment
Shown in accompanying drawing 1, at power termination and pipettor joint, an annular is set cuts off (in the frame of broken lines), inner chamber and interface are separated.Annular is cut off consistent with the head sucting body material, and one-shot forming in process of production also can cut off annular after the head sucting body moulding again and clamp-on the head sucting body privileged site.The head sucting body specification is identical with the existing pipettor suction nozzle in market, can coincide with existing pipettor.
