ABSTRACT
QC 3.16.2. Graduated cylinders for measurement of sample volumes must have a tolerance of 2.5% or less. In lieu of graduated cylinders, precalibrated containers that have clearly marked volumes of 2.5% tolerance may be used. The calibration of each new lot of precalibrated containers should be validated by selecting at least one container at random and checking the calibration using a previously verified graduated cylinder.
