  • Use lab grade glassware: Make sure to use Erlenmeyer flasks made of borosilicate glass, which is designed to withstand high temperatures and thermal shock. This type of glass is less likely to crack or shatter when exposed to heat.
  • Inspect the flask for scratches: Before heating the flask, inspect it for any scratches or cracks. If the glassware is damaged, it is more likely to break when exposed to heat.
  • Use a heating mantle or hot plate: When heating the Erlenmeyer flask, use a heating mantle or hot plate instead of placing it directly on the stove. This will help distribute the heat evenly and prevent hot spots that could cause the glass to break.
  • Heat the flask slowly: When heating the flask, start with a low heat setting and gradually increase the temperature. This will help prevent thermal shock and reduce the risk of the glass breaking.


  • Don’t heat the flask too quickly: Avoid heating the flask too quickly, as this can cause thermal shock and cause the glass to crack or shatter.
  • Don’t touch the flask with bare hands: When the flask is hot, don’t touch it with bare hands. Use heat-resistant gloves or tongs to handle the glassware.
  • Don’t place the flask directly on the stove: Placing the flask directly on the stove can cause hot spots and increase the risk of the glass breaking. Use a heating mantle or hot plate instead.
  • Don’t use damaged glassware: Using a flask with scratches or cracks can increase the risk of the glass breaking when exposed to heat.
