Description

Technical Field

[0001] The utility model relates to the technical field of pipettes, and particularly relates to a pipette. Background Art

[0002] A pipette is a type of liquid transfer device, commonly used in laboratories for transferring small or trace amounts of liquid. Different specifications of pipettes are equipped with different sizes of pipette tips. Pipettes produced by different manufacturers may have slightly different shapes, but their working principles and operating methods are basically the same. Pipettes are precision instruments and should be handled with care during use and storage to prevent damage and avoid affecting their measuring ranges.

[0003] The Chinese Patent Network discloses a cell pipette with the publication number: CN220345869U, which includes a gun body. The anti-touch mechanism includes a limit sleeve arranged on the outer side of the gun body. Connecting blocks are fixedly connected to both sides of the gun body. Inner cavities are opened in the connecting blocks. Slide holes are opened on the sides of the two inner cavities away from each other. Sliders are slidably connected in the slide holes. Springs are fixedly connected to the tops of the sliders. L-shaped plates are fixedly connected to the sides of the two sliders away from each other. In the utility model, by covering the limit sleeve on the top of the test tube, the moving trajectory of the gun body is limited, so that it can only move up and down and will not be horizontally skewed. The gun body is compressed, and the pipette tip of the gun body enters the test tube to transfer or drop cell liquid. After the operation is completed, the gun body is released and directly removed, ensuring that the pipette tip of the gun body will not touch the test tube during the operation of dropping cell liquid or subculture, thus avoiding cross-infection of cells.
