TECHNICAL FIELD

[0001] The utility model relates to the field technology field of laboratory instrument, concretely is a flexible pipette tip. BACKGROUND

[0002] In many biochemical experiments, the use of pipette gun is often indispensable, and the tip of the pipette gun is also a necessary product. However, the traditional pipette gun tip is made of hard plastic material, and it is difficult to fold the hard tip when folding the tip for plate streaking, coating or other operations. And because of its high hardness, folding the tip with the pipette gun will cause the front end of the pipette to bend to some extent, which can easily damage the pipette and shorten its service life.

[0003] Therefore, it is necessary to provide a tip that is easy to bend, flexible, practical and can effectively improve the use range and service life of the pipette gun. INVENTION CONTENTS

[0004] The utility model aims at providing a flexible pipette tip to solve the problems in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a flexible pipette tip, comprising a tip liquid storage part, the tip liquid storage part is made of flexible material and has a certain elasticity, easy to bend, the pipette connecting part can use hard material or flexible material with good elasticity to ensure tight connection with the pipette, and the surface of the tip body has several annular smooth protrusions to facilitate the use when coating the bacterial colony.

[0006] Preferably, the annular smooth protrusions are used to bend the gun head after injecting the bacterial liquid into the culture medium, and then used for coating the bacterial liquid.

[0007] Preferably, the annular smooth protrusions are integrated with the tip when making the tip mold, and are made of the same flexible material, and the protrusions are smooth and not sharp.

[0008] Preferably, the annular smooth protrusions provide an attachment support point between the tip and the mouth of the test tube or other container during normal use, which can play a role in preventing shaking to some extent. The gun head is compatible with the traditional pipette gun and can be easily replaced.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] Firstly, when the pipette gun tip needs to be folded for streaking and coating operations, folding will be easier and smoother, saving time to avoid the drying of the bacterial liquid on the culture medium and causing the culture to fail.

[0011] Second, the traditional colony coating needs to use alcohol lamp, inoculation platinum needle, etc., if the sterile pipette tip is directly coated, the use of experimental instruments can be reduced, and the damage of platinum wire overheating to the bacterial strain can be avoided.

[0012] Third, the damage to the pipette gun when folding the hard tip can be avoided, so that the service life of the pipette can be improved, and the cost can be reduced.

[0013] Fourth, the circular smooth protrusions on the main body of the tip can provide certain attachment sites and reduce the interference caused by shaking when using the pipette.

[0014] Fifth, in summary, the use of flexible tips can improve experimental efficiency, enhance experimental flexibility, reduce pollution, reduce cost, meet the concept of sustainable development, and can be widely used in various experiments. BRIEF DESCRIPTION OF DRAWINGS
