Q: Can it be heated directly over an open flame?

A: No. It is recommended to use laboratory heating equipment such as a heating mantle, oil bath, or water bath, and avoid sudden temperature changes to reduce thermal shock risk.

Q: Can it be used for vacuum applications?

A: It can be used for routine reduced-pressure experiments. Before use, ensure the glassware is undamaged and the system is properly sealed.

Q: How should it be cleaned and stored?

A: Clean with a mild detergent and a soft brush. Allow it to dry completely before storing in a cool, dry place.

Q: What should be noted during use?

A: Do not overfill the flask. The liquid volume is generally recommended to be below two-thirds of the total capacity.

Q: What should be checked before use?

A: Inspect the flask for cracks, chips, or other damage, and ensure all connections are securely fitted before operation.
