NEUTRAL GLASS<\/h2>\n

LBG N is a neutral borosilicate glass with high chemical resistance. Its coefficient of expansion
linear average is 8.0-10-6 K-1. It is used in products which are not intended to be heated directly but which must have a high mechanical resistance (mortars, desiccators, Kitasate flasks...) and in some volumetric materials (e.g. pipettes, burettes...).<\/p>\n

BOROSILICATE GLASS<\/h2>\n

LBG 3.3 is a borosilicate glass with a minimum silica content of 80% and a very low coefficient of expansion (3.3-10-6 K-1) which belongs to the group of \"3.3\" borosilicates as defined in ISO 3585. It is used in products where chemical resistance, mechanical strength and resistance to sudden changes in temperature must be combined, and because of this unique combination of properties it is the reference glass type from which most laboratory products are made.
