Cleaning instructions for volumetric glassware

These laboratory devices with graduations and imprints can be cleaned manually or by machine. When cleaning please make sure that the rinse bath temperature does not exceed 70 °C in use with alkaline detergents. In addition, the retention period should be reduced to a minimum.

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

Our recommendation for cleaning is water with a temperature of more than 90 °C without chemical additives (hot water cleaning). Please avoice rapid temperature changes when using measuring instruments made of soda lime glass.
