Glassware Technical

Glass is an inorganic mixture of metal oxides fused together at high temperatures, which upon cooling, solidifies into the clear, rigid, non-crystalline, versatile material known widely across the globe.

Pyrex Borosilicate Glass
All Pyrex, Quickfit, SVL and many MBL branded SciLabware products are manufactured from borosilicate glass (unless otherwise stated).

Pyrex is a borosilicate glass which meets the specifications of 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

Due to the demanding conditions that borosilicate glass is subjected to, maximum chemical toughness, minimum thermal expansion and high resistance to thermal shock make Pyrex the ideal material for use in the laboratory.

A profusion of SciLabware Ltd products also conform to other standards set out for laboratory glassware; for example beakers comply to ISO 3819 and volumetric flasks comply to ISO 1042 and DIN 12664. Typically these standards will specify not only glass type, but also dimensional detail, volumetric accuracy and tolerances.
