Glass quartz VN-100
Quartz glass possesses unique complex of valuable physical and chemical properties: high optical homogeneity, small light absorption (usual window glass absorbs as much light, how many and quartz glass 100 m thick), resistance to ionizing radiation and laser radiation of high intensity, in low thermal expansion coefficient, all products from quartz glass thermally and are chemically steady, are not affected by organic and inorganic acids, except hydrofluoric and orthophosphoric (heated to temperature over 300 °C).
Products from quartz glass are operated in the conditions of high temperatures and pressure (working temperature to 1250 °C), dynamic and vibration loads, kinetic heating and quenching, nuclear and space radiations. All products correspond to GOST 19908-90.
The glass of VN is intended for carrying out different analytical works, preparation of solutions,
heating of liquids, approximate measuring off of liquids etc.
The ware from quartz glass possesses small light absorptivity (passes both visible, and UV rays).
It is applied to work with acid and neutral substances at temperatures up to 1250 °C.
The glass of VN is issued according to requirements of GOST 19908-90 "Crucibles, bowls, glasses, flasks, funnels,
test tubes and tips from vitreous silica. General technical specifications".
