WHEATON Glass Types The glass products in this catalog are made from many different glass formulations. Following are brief definitions of these glass types and descriptions of their characteristics. 180 Glass: An exceptionally clear borosilicate glass of high chemical durability, which has been especially formulated for the lowest background count. 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. This glass type is used in the manufacture of specialty tubing containers. 200 Glass: Also referred to as 33 expansion low extractable borosilicate glass, is a clear borosilicate glass with exceptional thermal endurance that meets the requirements for ASTM Type I, Class A. This glass also meets USP Type I Glass Grains, USP Arsenic, EP Type I Glass Grains (Test B), and EP Arsenic, as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. This glass type is used in the manufacture of tubing containers and laboratory glassware. Some containers may also be tested for compliance to the current USP Type I Surface Test and EP Type I Surface Test (Test A). Compliance to these tests will be noted on the certificate of compliance for that item. 300 Glass: A chemically resistant clear borosilicate glass that meets the requirements for ASTM Type I, Class B. This glass also meets USP Type I Glass Grains, USP Arsenic, EP Type I Glass Grains (Test B), and EP Arsenic, as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. This glass type is used in the manufacture of tubing containers. Some containers may also be tested for compliance to the current USP Type I Surface Test and EP Type I Surface Test (Test A). Compliance to these tests will be noted on the certificate of compliance for that item. 320 Glass: A similar composition to 300 Glass except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. 400 Glass: A clear borosilicate glass that falls well within the limits for USP Type I Glass Grains, USP Arsenic, EP Type I Glass Grains (Test B), and EP Arsenic, as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. This glass type is used in the manufacture of molded bottles. Some containers may also be tested for compliance to the current USP Type I Surface Test and EP Type I Surface Test (Test A). Compliance to these tests will be noted on the certificate of compliance for that item. 500 Glass: Similar to the 400 Glass formulations except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. 800 Glass: A superior soda-lime clear glass that meets the requirements for USP Type III Glass Grains, USP Arsenic, EP Type III Glass Grains (Test B), and EP Arsenic, as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia. This glass type is used in the manufacture of molded bottles. Some containers may also be tested for compliance to the current USP Type III Surface Test and EP Type III Surface Test (Test A). Compliance to these tests will be noted on the certificate of compliance for that item. 900 Glass: Similar in formulation to 800 Glass except amber color for light sensitive applications. Meets UV light protection limits as specified in the current revisions of the U.S. Pharmacopeia and European Pharmacopeia.
