How To Classify Pharmaceutical Glass Containers USP Type I II III?

USP Type-Pharmaceutical glass containers can be classified as USP Type I, II, III.


Type I-Borosilicate glass represents the least reactive glass.
Type I glass has the least pH shift. (Lowest leaching characteristics)
Coefficient of Expansion = 3.3 or 5.0 or 7.0


Type II - is de-alkalized soda-lime glass with higher levels of sodium hydroxide and calcium oxide.


Type III - soda-lime glass - cannot be autoclaved.
Coefficient of Expansion = 9.0
