Chromatography glass vial material standard
That silicate glass contain at least 5% boron oxide is referred to as Borosilicate glass. The ingredient of boricoxidation in glass is resistant to extreme temperature and chemical corrosion. Type I borosilicate has a minimum pH shift. It is highly resistant to water, neutral and acidic solutions, concentrated acid and acid mixtures, and chlorine, bromine, iodine and organic materials. The borosilicate glass has superior chemical characteristics than most metals and other materials. It can resistance above 100 temperatures of prolonged exposure and above 100 ℃. The linear of expansion of type 1 clear borosilicate glass is 33 or 51, and the linear expansion of the type 1 amber borosilicate glass is 51.
