DURAN® laboratory bottles

The DURAN® evolutionary process is, like all others, characterised by diversification and branching. At its core is the Original GL 45 laboratory bottle, made of borosilicate 3.3 glass, with easy to read scales and large labelling field for easy marking, in fired-on, highly durable white ceramic.

Borosilicate glass 3.3 is an attractive material that offers inexhaustible design possibilities. Very high chemical resistance, virtually inert behaviour, transparency, high usage temperature, minimal thermal expansion, and the resulting high resistance to thermal shock, are its most significant properties.

Since the introduction of the GL 45 laboratory bottle in 1972, DURAN® bottles have been consistently developed and improved. A broad range of high quality products and systems are now available. Numerous variants, and comprehensive original equipment from DURAN®, allow for almost unlimited applications.
