Amber: A brown color glass that absorbs nearly all radiation with wavelengths shorter then 450mm. Amber glass offers excellent protection from ultraviolet radiation. This is critical for protection of controlled samples and specimens.
Cobalt: A blue colored glass which results from copper or cobalt being added to the liquid molten mixture.
Green : Green glass is achieved as a result of oxidized iron chromate being added to the liquid molten mixture.
Frosted Glass: Frosted glass is achieved when any color glass is treated. The result gives the glass a new look and feel.
Flint Glass: Flint glass is clear colorless glass.
Glass Types:
"180" 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 is extractable borosilicate glass, which 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 is added 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 is added for light sensitive applications. Meets UV light protection limits as specified in the current revision of the U.S. Pharmacopeia.
Other Glass Types:
Borosilicate Glass: Borosilicate is one of the most popular used glasses. One reason for Borosilicate’s popularity is its low expansion coefficient; this characteristic allows the glass to resist breakage caused by temperature changes. The low expansion coefficient allows the glass to be used for such products and lab equipment, cookware, and glassware.
Soda Lime Glass: Soda Lime is another popular glass; this glass is typically used for drinking glasses, tableware, bottles, jars, and windowpanes. Soda Lime glass is composed of silica, calcium, and soda. The more silica in the glass mix the greater the resistance to thermal shock, although it does not compare to Borosilicate’s thermal resistance.
Lead Glass: Lead Glass tends to be a softer glass, allowing for the glass to be cut showing off the glasses beauty. Lead glass tends to not withstand sudden temperature changes, or high temperatures. Lead glass is commonly used for glasses, and decorative figurines.
