DURAN® Volumetric Flask Gelas Ukur

DURAN® volumetric flasks are used for the accurate measurement of specific quantities of liquids. They are volumetric analysis aids in quantitative laboratory work. 
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 class “A” Volumetric flasks are calibrated individually, but are available with two different types of certificates, one type is supplied with a certificate of the production lot (also available online), the other type with individual certificates.

The accuracy class “B” products have a white print. For these products only a general glass specification is available.DURAN® Volumetric Flask
