Cleaning of volumetric glassware is necessary to not only remove any contaminants, but
to ensure its accurate use. The film of water which adheres to the inner glass wall of a container
as it is emptied must be uniform.
Rinse the volumetric glassware two or three with tap water, then a small amount of dilute
detergent solution (A buret or test tube brush can be used in the cleaning of volumetric
glassware), several rinsing with tap water, and two or three rinsing with distilled water are
generally sufficient if the glassware is emptied and cleaned immediately after use.
Pipets and burets should be rinsed at least once with the solution with which they are to
fill before use.
