DURAN®glass Very high chemical resistance, nearly inert behaviour, a high usage
temperature, minimal thermal expansion and the resultant high resistance to thermal shock
are the most significant properties of DURAN® glass. This optimal physical
and chemical performance makes DURAN® the ideal material for use in the
laboratory and for the manufacture of chemical apparatuses used in large
scale industrial plants. It is also widely used on an industrial scale in all
application areas in which extreme heat resistance, resistance to thermal
mechanical strenght and exceptional chemical resistance are required.
DURAN® properties are specified in DIN ISO 3585. In contrast to other
glasses, DURAN® is notable for its highly consistent, technically reproducible

DURAN® glass is highly resistant to water, acids, saline solutions, organic
substances and also halogens such as chlorine and bromine. The resistance to
alkali is also relatively good. Only hydrofluoric acid, concentrated phosphoric
acid and strong alkalis cause appreciable surface removal of the glass (glass
corrosion) at elevated temperatures. Due to the nearly inert behaviour, there
are no interactions (e.g. ion exchange) between medium and glass and any
spurious influence on experiments is thereby effectively excluded.
