1.0 Volumetric Glassware: 1.1. Introduction. Volume measurement is one of the routine tasks in the laboratory. Typical volumetric instruments, such as one-mark and graduated pipettes, burettes, volumetric flasks and cylinders are therefore part of the basic requirement.
Calibration of Volumetric Glassware An important trait of a good analyst is the ability to extract the best possible data from their equipment. For this purpose, it is desirable to calibrate your own volumetric glassware (burets, pipets, flasks, etc.) to measure the exact volumes delivered or contained.
