Product Overview
Volumetric flasks are available in two different accuracy Classes: Class A and Class B. The two Classes differ in the accuracy of measurement with Class A being the highest accuracy, and Class B is approximately half that of Class A. The volumetric flasks with accuracy Class A have a blue print for clear glass products and a white print for amber versions. The accuracy Class B products have a white print. For these products only a general glass specification is available.
