Explanation of Glass Types and when they are required.

Glass is designated as a particular Type if it complies with the requirements of a specific pharmacopoeia, e.g. EP (European Pharmocopoeia), USP (United States Pharmacopoeia) and JP (Japanese Pharmacopoeia).

Pharmaceutical Glass Types

TYPE I GLASS / TYPE 1

Also known as "neutral," type 1 is a borosilicate glass with good chemical resistance. It is used for pharmaceuticals requiring the least reactive containers.

TYPE II GLASS / TYPE 2

A treatment applied to the internal surface of the glass reduces ion exchange, making this category suitable for solutions administered intravenously.
