[0002] A pipette is a widely used instrument in laboratories, healthcare and other fields, mainly used to accurately transfer a specific volume of solution. It is usually made of a thin glass tube with a bulged middle part. The lower end is sharp and used to absorb and release liquids, while the neck of the tube at the upper end is engraved with markings that indicate the exact volume to be transferred, providing precise guidance for the experimenter.
[0003] The transfer device in the prior art has some shortcomings in the transfer process of the pipette. The prior art cannot buffer the pipette during the transfer process, which causes the liquid to produce violent fluctuations or splashes during the transfer process, making the pipetting unstable, making it difficult to accurately transfer the required volume.
