Neutral glass test tubes. Made of neutral glass LBG N. Without rim. LBG N is a neutral borosilicate glass with high chemical resistance. Its average coefficient of linear expansion is 8.0-10-6 K-1. It is used in products which are not intended to be heated directly but must have a high mechanical strength (mortars, desiccators, Kitasate flasks...) and
in some volumetric materials (e.g. pipettes, burettes...). In different sizes.
