Description

A kind of disposable more adaptation pipettes

Technical field

The utility model relates to a kind of pipette, specifically a kind of disposable more adaptation pipettes.

Background technique

Pipette is widely used in that cell culture, microculture, molecular biology etc. is clinical and scientific experiment, in experiment It is common to be used to measure reagent, mainly there are 7 kinds of capacity it can be selected that including 1.0,2.0,5.0,10.0,25.0,50.0 and 100.0ml。

Although existing pipette has more Capacity Selection, but using in the presence of not in some particular/special requirement experimentations Just.Especially in cell culture experiments, often need to carry out porous plate to aspirate the operation of culture solution, existing pipette needs to select It selects bore sizeable series in pipette bottom end to be operated according to the size of orifice plate, however bore has been selected suitably to move Liquid pipe is not often able to satisfy liquid relief demand on capacity.Therefore, operator needs to be repeated extraction or pipetting, and Operation requires the pipette more renewed every time, substantially reduces liquid relief efficiency in this way, while frequent replacement pipette also increases Experimental cost.

Therefore a kind of disposable more adaptation pipettes are provided, to solve the above problems.

Utility model content

The purpose of this utility model is to provide a kind of disposable more adaptation pipettes, to solve to mention in above-mentioned background technique Out the problem of.

To achieve the above object, the utility model provides the following technical solutions:

It is a kind of it is much more disposable be adapted to pipettes, including tube body and more adaptation ozzles, more adaptation ozzles are fixed on described Bottom, more adaptation ozzles are successively arranged top mostly adaptation ozzle end, middle part from top to bottom and are adapted to ozzle end and bottom more Portion is adapted to ozzle end more.

Further embodiment: it is equipped with filtering plug at the top of the tube body, is equipped with cotton filter core inside filtering plug.

Further scheme: the tube body and more adaptation ozzle ultrasonic weldings are fixed, and tube body is equipped with graduation mark.

Further scheme: the materials of the tube body and more adaptation ozzles are polystyrene.

Further scheme: the bottom is adapted to that ozzle end is interspersed to be fixed in the more adaptation ozzle ends in middle part more Portion, middle part are adapted to the interspersed top that is fixed in ozzle end more and are adapted to inside ozzle end more, and top is adapted to ozzle end, middle part more It is in small round table-like, the top mostly adaptation of the big lower end diameter of upper end diameter that mostly adaptation ozzle ends and bottom are adapted to ozzle end more The outer surface of ozzle end is equipped with the first friction plate, and the outer surface that middle part is adapted to ozzle end more is equipped with the second friction Plate, the outer surface that bottom is adapted to ozzle end more are equipped with third friction plate, and bottom is adapted to ozzle head bottom part centre bit more The place of setting offers nozzle.

Further scheme: first friction plate, the second friction plate and third friction plate are rectangle.

Compared with prior art, the utility model has the beneficial effects that

The utility model disposably more is adapted to pipette, and pipette bottom nozzle can be suitble to the orifice plate of multiple aperture, be applicable in model It encloses greatly, easy to use, liquid relief is high-efficient.
