What is the uncertainty in the measurement of a pipette?

The uncertainty in the measurement of a pipette typically arises from factors such as the accuracy of the calibration, the precision of the reading, and environmental conditions. It is often expressed as a percentage of the measured volume or as a specific volume range. For example, a micropipette might have an uncertainty of ±1% of the set volume, meaning that if you pipette 100 µL, the actual volume could vary by ±1 µL. Proper technique and regular calibration can help minimize these uncertainties.
