Glass grades are classified in hydrolytic classes . We supply vials from the following classes: 1st hydrolytic class Glass grades made from borosilicate, such as DURAN ®, Pyrex ®, Fiolax ® and others belong to this group. Glass of this class, which is often called neutral glass, has a very good chemical resistiance towards acid and neutral

What are the differences between “33 expansion” and “51

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.
