Technical Literature
ASGI Glass wares are made from carefully selected low alkali borosilicate glass raw material so that it is virtually free from impurities, particularly heavy metals. This means that no contamination of highly critical analysis solutions can occur during its laboratory use. ASGI Glass wares are made from genuine 3.3 Low Expansion Heat Resisting ASTM E-438 Type 1, Class "A", Borosilicate Glass which is by nature highly resistant to attacks from water, neutral & acids solutions, concentrated acids, mixtures of acids, chlorine, bromine, iodine & organic substances. Only Hydrofluoric acid, solutions containing fluoride ions ( e.g. Ammonium fluoride ), very hot phosphoric acid and alkaline solutions attack the surface of the glass, the degree of attack increases as the concentration and temperature rise.
