The pipette is a commonly used instrument in laboratories. It is a measuring tool used to transfer liquid from one container to another. When conducting analytical testing research, a pipette is generally used to measure a small or trace amount of liquid.

Tips for using laboratory pipettes:

1. Maintain the correct posture when pipetting; do not hold the pipette tightly all the time, use a pipette with a finger hook to help relieve hand fatigue; change hands frequently if possible.

2. Check the sealing condition of the pipette regularly. If the seal is found to be aging or leaking, the seal ring must be replaced in time.

3. Calibrate the pipette 1-2 times a year (depending on the frequency of use).

4. For most pipettes, a layer of lubricating oil should be applied to the piston before and after use to maintain the seal; for conventional range pipettes, ideal sealing is also achieved without lubricating oil.

After use, the adjustable pipette must be adjusted to the maximum range and then hung up. It can be hung on a special bracket or on the metal crossbar of the laboratory bench cabinet.
