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.These flasks are RAY-SORB® processed to protect your light-sensitive contents from short-length light waves.
