Pipette maintenance method

Pipettes are widely used as a tool for micro-liquid transfer in biological laboratories. How to calibrate pipettes, repair pipettes, maintain pipette equipment, and what are the methods of disinfection and sterilization?

1. After each use of the pipette, try to adjust the volume of the pipette to the MAX scale so that the spring is in a relaxed state.

2. If the pipette needs to be subjected to high temperature, before high-temperature disinfection, it must be confirmed whether the pipette is sterilized as a whole or half.

3. You can use the SmartCheck pipette verification instrument to calibrate the pipette, and the pipette calibration can be completed within 60 seconds.

4. For the calibration and maintenance of pipettes within the warranty period, they can be handed over to the after-sales customer service of the supply chain in batches for free service.

5. It is also important to develop a good pipetting operation habit to maintain the pipette. The self-maintenance of the pipette can be cleaned with soapy water or 60% (CH3)2CHOH, then washed with distilled water, and dried naturally. Can.

6. Check the pipette for leakage when using it. If the liquid leaks, you can find the cause from the following aspects:

1. Whether the pipette tip is accurately matched;

2. Whether the function of the spring piston inside the pipette gun is normal;

3. For organic solvents, volatile liquids, etc., it may also be caused by the problem of saturated vapor pressure. If you encounter this kind of problem, you can try to aspirate and release the liquid several times, and then pipette again.
