1 Like graduated cylinders, a pipette should not be used to measure volumes that are less than 50% of its capacity. 2  Therefore, pipettes are suitable for measuring volumes of as little as 0.5 mL up to as much as 10 mL. 3  Micropipettors (or automatic pipettors) are generally used to measure volumes of 1 mL or less.
