Calibration Levels Explained

Calibration levels are derived from a number of gravimetric weighings taken at different volumes. For variable volume pipettes it is recommended that weighings be taken at the nominal (maximum) volume, the mid-point (50% of nominal) and the minimum volume (10% of nominal). Weighings can also be taken at the maximum and minimum volumes only, or even at just the mid-point volume. For fixed volume pipettes, weighings can only be taken at the fixed volume.
