Do not scrub the inside of volumetric glassware such as burettes, volumetric pipettes, measuring flasks, and conical measures with a brush. This could cause a volumetric disorder. Volumetric glassware should be rinsed repeatedly with tap water.

For the same reason, volumetric glassware should not be dried by heating. Wash off chemical stains with a brush and sodium hydrogen carbonate. Dissolve stains of organic substances with a small amount of ethanol. Pour the washing waste of ethanol into the specific waste container.

How to wash glassware:
