Type I Glass

Containers made of type 1 borosilicate glass are generally used for preparations that are intended for parenteral (injection) administration. Highly resistant borosilicate glass.

Type II Glass

Treated soda lime glass.

Type III Glass

Soda lime glass

Type NP Glass

General-purpose soda lime glass

Weathering

The attack on glass surface by atmospheric elements.

Wide Mouth

The finish of a glass container in which the diameter is large relative to the diameter of the body.

Glass Types

180 – Glass This glass is an exceptionally clear borosilicate glass of high chemical durability, which has been especially formulated for the lowest background count while still at a reasonable cost. Great care has been taken to select only those ingredients for the batch that would not cause unwanted background count or color. Potassium as a separate element has been excluded from the batch to minimize K40. Special controls assure high quality and batch-to-batch uniformity.

200 – Glass, low extractable borosilicate glass, is a clear borosilicate glass with exceptional thermal endurance that meets the requirements for both USP and ASTM Type I, Class A, borosilicate glass.

300 – Glass is a chemically resistant clear borosilicate glass that meets all of the requirements for Type I glass as specified in the current revision of the U.S. Pharmacopeia.

320 – Glass is a similar composition to “300” except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revision of the U.S. Pharmacopeia.

400 – Glass is a clear borosilicate glass that falls well within the limits for Type I chemically resistance borosilicate glass, as specified in the current revision of the U.S. Pharmacopeia.

500 – Glass is similar to the “400” formulation except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revision of the U.S. Pharmacopeia.

800 – Glass is a superior soda-lime clear glass that meets requirements for Type III soda lime glass as specified in the current Revision of the U.S. Pharmacopeia.

900 – Glass is similar in formulation to “800” except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revision of the U.S. Pharmacopeia.
