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. Regularly check the sealing condition of the pipette. Once the seal is aging or leakage occurs, the sealing 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, before use and after using for a period of time, the piston should be coated with a layer of lubricating oil to maintain the tightness; for RAININ pipettes with regular range, it is also ideal without lubrication Tightness.
