Pyrex is used in lots of lab glassware – but what is the maximum temperature Pyrex should be used at?

A: Pyrex is suitable for use from -192°C to +500°C

This makes it an ideal choice for lab glassware which will be directly heated. Soda-Lime glass is less suitable for direct heating, so choose Pyrex where possible if you will be applying heat.

Beakers, test tubes and flasks that are made from Pyrex glass are suitable for direct heating by hotplate, heating mantle or bunsen burner.

Remember that heating and cooling should always be slow and steady – Pyrex can withstand huge temperature changes, but if they are too sudden it may still crack due to thermal shock.
