Description

Technical Field

[0001] The utility model relates to the technical field of biological and medical laboratories, and in particular to a sterilizing device for a pipette. Background Art

[0002] A pipette, also known as a pipette gun, is a measuring instrument that can transfer liquid from the original container to another container. It is widely used in biochemistry, molecular biology, biomedicine and other fields because of its accurate measurement, convenient operation and wide application range. According to the working principle, pipettes can be divided into gas piston pipettes and external piston pipettes. The gas piston pipette controls the expansion and contraction of the spring to push the piston, exhaust the air, and inhale the liquid to achieve the transfer of conventional aqueous solutions. It can also meet the daily experimental needs of the laboratory and has become a basic instrument in clinical diagnostic laboratories, biotechnology laboratories, pharmaceutical and chemical laboratories, environmental laboratories, food laboratories and other laboratories.

[0003] Currently, the pipettes sold on the market have various specifications, ranging from 0.1μL to 10mL, and single-channel, 6-channel, 8-channel, 12-channel and 16-channel. Due to the special structure of the pipette, improper operations such as pipetting exceeding the tip specifications, violent operation when blowing and mixing the liquid, and laying the pipette flat when the liquid is sucked can all cause contamination of the suction tube wall and affect the accuracy of the experimental data. Solving the contamination problem of the pipette has become an urgent problem.
