chemically inert and highly resistant
→ made up of boron and aluminum zinc
molecules
Type 1
chemically inert compared to borosilicate
glass
Type 2
durable to containers from acids to bases
Type 1
similar to type 2 but they are not plated
thus they do not have the enhance
chemical resistance
Type 3
used for oral and topical preparations
Type 4
Surface treated Soda-lime glass
Type 2
Ultra-resistant borosilicate glass
Type 1
Regular soda-lime glass
Type 3
General purpose soda-lime glass
