Cleaning of volumetric glassware

Laboratory glassware can be cleaned manually or by machine. When cleaning volumetric instruments and equipment with application-specific imprints, make sure that the rinsing bath temperature does not exceed 70 °C in use with alkaline detergents to avoid damages of the graduations and other prints like ring marks. In addition, the retention period should be reduced to a minimum.

Alkaline media in conjunction with temperatures above 50 °C and a longer retention period may cause volume changes due to the glass erosion and can destroy the imprints.

We recommend the cleaning of instruments in water with a temperature of more than 90 °C without any chemical additives (hot water cleaning). Instruments made of soda lime glass must not be exposed to rapid temperature changes. They have to be heated slowly and also cooled down slowly in order to avoid tension cracks.
