Problems solved by technology
[0002] During the use of the pipette, the tips of the pipette need to be replaced frequently. Once a pipette tip is contaminated, it will contaminate the pipette, which in turn will cause contamination of all subsequent pipette tips, which will cause crossover. Contamination, which makes the experimental data inaccurate

Embodiment Construction
[0007] See figure 1 , which includes a pipette tip body 1, the pipette tip body 1 is close to the connection ring surface 2 of the pipette gun and is equipped with two filter element structures arranged up and down: an upper filter element structure 3, a lower filter element structure 4, and an upper filter element structure 4. There is a cavity 5 between the lower filter element structure 4, and the upper filter element structure 3 and the lower filter element structure 4 are all composed of multi-layer high-density glass fibers.

The invention provides a pipetting gun head structure with filter elements. The pipetting gun head structure solves a problem that pollution of one pipetting gun head causes cross infection on a pipetting gun and other pipetting gun heads, and the pipetting gun head structure guarantees accuracy of experimental data. The pipetting gun head structure comprises a pipetting gun head body and is characterized in that the pipetting gun head body is close to two vertically-distributed filter elements which are installed on a connection ring face of the pipetting gun in a filled mode, the two vertically-distributed filter elements comprise an upper filter element structure and a lower filter element structure, a cavity is left between the upper filter element structure and the lower filter element structure, and the upper filter element structure and the lower filter element structure are both formed by assembling a plurality of layers of high-density glass fibers.
Description
technical field [0001] The invention relates to the technical field of cell culture structures, in particular to a pipette tip structure with a filter core. Background technique [0002] During the use of the pipette, the tips of the pipette need to be replaced frequently. Once a pipette tip is contaminated, it will contaminate the pipette, which in turn will cause contamination of all subsequent pipette tips, which will cause crossover. Contamination, thus making the experimental data inaccurate. Contents of the invention [0003] In view of the above problems, the present invention provides a pipette tip structure with a filter element, which prevents the contamination of one pipette tip from being cross-infected to the pipette gun and other pipette tips, ensuring the accuracy of experimental data. [0004] The pipette head with filter element has a technical scheme as follows: it includes a pipette head body, and it is characterized in that: the connecting ring plu...
