Woulff Bottle, Borosilicate Glass 3.3, GL 45

The Woulff bottle made of high-quality borosilicate glass 3.3 has been specially developed for demanding laboratory applications. It features a standardized GL 45 screw cap and is equipped with a protective plastic coating that increases mechanical stability and provides additional safety in case of glass breakage.

Due to its characteristic bottle shape with two side tubulations, the Woulff bottle is ideal for gas scrubbers, absorption processes, distillations, and other synthetic working techniques. The borosilicate glass 3.3 used is characterized by excellent chemical resistance, low thermal expansion, and high thermal shock resistance.

The Woulff bottle is available in various nominal volumes from 500 ml to 20000 ml, enabling a wide range of applications – from analytical laboratory scale to preparative synthesis.
