LBG 3.3 is borosilicate glass with a minimum content in silica of 80% and a low expansion coefficient (3.3•10-6 K-1) included in the 3.3 borosilicate group, as defined in ISO 3585 standard. It is used in products where chemical and mechanical resistance is to be combined with resistance to sudden temperature changes. This particular combination of properties makes this type of glass the most used in labware.
