Safety Tips:

  1. Always replace glass laboratory containers that have become scratched or abraded. These defects will make the glass prone to breakage while in use.
  2. The maximum working temperature for PYREX glassware is 490°C. However, once the temperature exceeds 150°C, ensure that heating and cooling is achieved in a slow and uniform manner.
  3. Do not use hydrofluoric or hot phosphoric acid in glass.
  4. Hot alkalis will etch glass.
