While Erlenmeyer flasks are generally safe and easy to use, there are a few precautions to keep in mind:

• Heat:When heating Erlenmeyer flasks, avoid direct flame contact to prevent cracking. Use a hot plate or Bunsen burner with a flame spreader.
• Chemicals:Be aware of the compatibility of the flask material with the chemicals you are using. Some chemicals may react with the glass or plastic, causing damage or contamination.
• Safety:Always wear appropriate personal protective equipment, such as gloves and safety glasses, when handling Erlenmeyer flasks and chemicals.
• Pressure:If the flask is being used under pressure, ensure it is rated for the appropriate pressure and is securely closed.
• Cleaning:Thoroughly clean Erlenmeyer flasks after each use to prevent contamination. Follow the cleaning instructions provided earlier.
