A flat-bottom boiling flask is a common piece of laboratory glassware used in a wide range of chemical experiments. It is a round-bottomed flask with a flat base, providing stable support on a benchtop or hot plate. This design distinguishes it from traditional round-bottom flasks, which have a spherical base and require a ring stand and clamp for support during heating.
Flat-bottom boiling flasks are typically made of borosilicate glass, a type of glass known for its high resistance to thermal shock, making it suitable for heating and cooling applications. They are commonly used for carrying out chemical reactions, such as heating, refluxing, and distillation. The round bottom allows for even heat distribution and efficient mixing when using a magnetic stirrer.

Material of boiling flask:
- Glass (Most common: borosilicate glass)
- Corning Glass (A specific type of borosilicate glass known for its high resistance to thermal shock)
Usage of boiling flask:
- Chemical Reactions: Carrying out chemical reactions, including heating, refluxing, and distillation.
- Heating Liquids: Heating liquids over a heat source like a hot plate or Bunsen burner.
- Distillation: Used as the boiling flask in distillation setups.
How to Use boiling flask:
- Heating: Use a heat source like a hot plate or Bunsen burner, ensuring even heating.
- Support: Use a clamp and ring stand to securely support the flask during heating.
- Stirring: Use a magnetic stirrer or stir bar for efficient mixing during reactions.
- Cleaning: Thoroughly clean the flask after each use to remove any residual chemicals.
When using a flat bottom boiling flask, it’s essential to use appropriate safety precautions. Always wear appropriate personal protective equipment, such as safety glasses and gloves. Use a heat source like a hot plate or Bunsen burner with caution, and ensure the flask is securely clamped to a ring stand to prevent tipping.
