Mar 30, 2012 · Clear glass of first hydrolytic class is divided into two categories: “33 expansion” (Type 1, Class A) and “51 expansion” glass (Type 1, Class B). The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher temperatures when manufacturing auto sampler vials.

Clear Glass of 1st hydrolytic class is differentiated by 33 expan-sion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expan-sion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher tempera-tures. These
