KIMBLE® RAY-SORB® Volumetric Flask, Amber, Class A, Heavy Duty, Wide Mouth With Pennyhead Glass Stopper 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.
