1. Regular calibration and maintenance should be carried out according to the frequency of use and the environment of the laboratory micropipette, and it should be calibrated and maintained once every quarter.
2. Before starting work every day, check whether there is dust or dirt on the outer surface of the pipette. If there is, wipe it off carefully. Do not use fire to grill any part of the micropipette, and do not absorb solutions with a temperature higher than 700C to avoid steam intrusion and corrosion of the piston.
3. After general use, clean it with distilled water and neutral detergent or 60% isopropanol. Then repeatedly wash with distilled water, remove detergent or isopropanol, and dry. A certain amount of lubricant can be used at the piston after cleaning.
4. When it is heavily contaminated, follow the steps in the relevant manual of the pipette to disassemble the sampler and clean it. The autoclaved part of the pipette should be autoclaved, but it should not be overheated or squeezed to avoid deformation and damage to the pipette.
5. Check the accuracy of the pipette by yourself regularly, and send it to the factory for repair in time if there is any problem.
Pipettes are mainly used in scientific research departments such as environmental protection, medicine, food hygiene, etc., for sampling or adding liquid in biochemical analysis and laboratory tests. It is a piston type straw that works by using the principle of air discharge. The capacity of the pipette is determined by the distance the piston moves in the piston sleeve, and the liquid is sucked out of the container and moved to a measuring instrument in another container. Correct operation and the use of pipettes can improve work efficiency and prevent fewer errors.
