Q: What is the highest and lowest temperature that Pyrex glassware should be exposed to?
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. Pyrex is borosilicate glass which makes it highly temperature resistant. Soda-Lime glass is less suitable for direct heating, so choose Pyrex where possible if you will be applying heat. Not only is Pyrex heat resistant, it also has high levels of chemical resistance to acids and alkalis, making it a versatile choice for your lab.
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.
