   Good Laboratory Practice: When using a volumetric flask, a solution should be diluted stepwise. The solution to be diluted is added to the flask, and the diluent (usually distilled water) is added to fill the flask about two-thirds (ensuring that any reagent on the ground glass lip is rinsed down).

   How is volumetric glassware tested?

   • The table below indicates the appropriate ISO documentation for use and testing of capacity of volumetric glassware. In summary, the general procedure is based upon a determination of volume of water either contained in or delivered by the vessel. This volume of water is based upon knowledge of its mass and its tabulated density. 1.7.

   How much water should be used for rinsing analytical glassware?

   • About 1/5 of the volume of the pipette or burette is adequate for each rinsing. A volumetric flask if wet should be rinsed with 3 portions of water prior to use. Analytical Glassware should not be dried in an oven or with a towel or by rinsing with a volatile organic solvent e.g. acetone (used in organic chemistry labs).
