Gravimetric pipette calibration is one of the most accurate ways to calibrate a pipette and is by far the most widely-used method.
The technique involves weighing the volume of liquid (de-ionised water) dispensed by the pipette (known as an "aliquiot") and converting the weight into the equivalent volume using what is known as the Z-FACTOR (which is very closely related to density and specific gravity).
Readings are repeated (usually 5 are taken) for three volumes that cover the range of the pipette (Low - 20%, Medium - 50% and High - 90%). So, for example, if a 200 µl pipette were being calibrated, we would record the following measurements:
- 5 readings at 40 µl
- 5 readings at 100 µl
- 5 readings at 180 µl

Calibration Toolbox ADO - Pipette Calibration Module
Caliso offers you the Pipette Calibration Module, an add-on to Calibration Toolbox ADO which is designed to reduce significantly the amount of work involved. This is achieved by automatically recording water weight readings from your laboratory balance and then performing all necessary calculations so that you don't have to.
Once you've obtained your measurements and the calculations have been performed, a PDF calibration certificate is only a few clicks away.
