Tips: Steps for pipette calibration 

Here are the steps for pipette calibration:

1. Select calibration liquid
   Choose a liquid with stable properties, usually deionized water, for calibration.
2. Check equipment requirements
   Ensure you have a high-precision balance to weigh the liquid dispensed from the pipette.
3. Perform the calibration
   Aspirate liquid: Use the pipette to draw a set volume of liquid.
   Dispense liquid: Transfer the liquid into a container.
   Weigh the liquid: Use the balance to measure the mass of the dispensed liquid.
4. Calculate the volume
   Based on the measured mass and the liquid's density, calculate the actual volume dispensed.
5. Compare with nominal volume
   Compare the calculated volume with the pipette's specified volume. Note any discrepancies.
6. Adjust if necessary
   If there's a significant deviation, adjust the pipette if it is adjustable, or replace it if needed.
7. Repeat if necessary
   Repeat the calibration process with different volumes to ensure accuracy across the pipette's range.
8. Record calibration results
   Document the calibration results for future reference and quality control purposes.
