Abstract

The utility model discloses a plug core disposable transfer pipette, which comprises a transfer pipette main body, wherein the rear end of the transfer pipette main body is provided with an end plug, and a filter plug core is arranged in the end plug. Because the disposable transfer pipette is provided with a hydrophobicity filter core not through the end plug, the plug core disposable transfer pipette plays the role of preventing form sucking reversely and overflowing through the filter plug core, and the use is reliable.

Description

The disposable pipette of plug core
Technical field
The utility model relates to a kind of disposable pipette.
Background technology
Disposable pipette adopts transparent polymer material polystyrene (GPPS) to make, and is widely used in clinical and scientific experiments such as tissue cultivation, bacteriology.Present disposable pipette, filled in cotton in its pipe end routine, in use, the electronic pipettor that can cooperate each class standard, prevent suck-back and spill-over simultaneously, still, adopt the structure of cotton for the plug core, still there is of non-ideal use, insecure situation, in use still has the phenomenon of suck-back or spill-over.
Summary of the invention
In order to solve the above problems, the purpose of this utility model be to provide a kind of easy to use, fill in the disposable pipette of core reliably.
The technical scheme that the invention for solving the technical problem adopted is:
The disposable pipette of plug core comprises pipette body, and the rear end of described pipette body is equipped with an end plug, is provided with a hydrophobicity filter core in the end plug.
The beneficial effects of the utility model are: because the end plug of this disposable pipette is equipped with the hydrophobicity filter core, play to prevent the suck-back that in use occurs or the situation of spill-over by this filter core, use reliably.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the fractionation structural representation of the utility model pipette;
Fig. 3 is the I portion enlarged drawing of Fig. 1.
The specific embodiment
With reference to Fig. 1-Fig. 3, the disposable pipette of plug core of the present utility model comprises pipette body 1, and the rear end of described pipette body 1 is equipped with an end plug 2, is provided with a hydrophobicity filter core 3 in the end plug 2.
As preferred implementation, described end plug 2 comprises Embedded Division 20, shoulder 21 and back connecting portion 22, end plug 2 is fixed on the afterbody of pipette body 1 by Embedded Division 20 interlockings, be provided with a through hole 23 in Embedded Division 20, shoulder 21 and the back connecting portion 22, filtering plug core 3 is installed in the through hole 23, it is rational in infrastructure, and assembling is simple, convenient.
Certainly, the invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
