Part of a comprehensive range of laboratory articles with interconnecting joints, enabling simple to complex chemistry set-ups to be easily constructed and allowing a variety of analytical, development or educational tasks to be undertaken. Precision-engineered, ground glass joints with a standard taper and smooth surface ensure complete interchangeability of elements with the same joint size and the highest standards of leak-tightness.

Borosilicate glass, with a low coefficient of expansion, excellent chemical and heat resistance. It conforms to the following standards:

ISO 3585, DIN 12217 – Type 3.3 borosilicate glass
ASTM E-438 Type 1 – Class A borosilicate glass
US Pharmacopoeia – Type 1 borosilicate glass
European Pharmacopoeia – Type 1 glass

Further technical details are available on request.

Joint sizes are designated XX/XX, the prefix (XX/-) being the small diameter of the cone or socket and the suffix (-/XX) being the cone or socket height, i.e. size 24/29 has a 24mm diameter at its smallest point and the overall cone or socket height is 29mm.
