Round-Bottom Flask
Round-Bottom Flask
A round-bottomed flask is a common piece of laboratory glassware used to hold liquids during heating or reactions.
Heating Source
Heating Source
The heating source provides the energy to vaporize the liquid in the round-bottom flask. This can be a Bunsen burner, hot plate, or other heat source.
Condenser
Condenser
A condenser is a specialized tube used to cool vapors and condense them back into a liquid. Typically, water flows through the condenser to cool the vapors efficiently.

Study Notes
Fractional Distillation Apparatus
- A diagram shows a fractional distillation setup
- A round bottom flask contains a liquid mixture
- The flask is heated using a Bunsen burner
- The vapor rises through a fractionating column
- The column is packed with glass beads or metal wool
- The vapor cools and condenses on the packing material
- Different components of the mixture condense at different temperatures
- The condensed liquid drips down the column
- The more volatile component comes out at a lower temperature
- The column separates the mixture
- A receiving flask collects the separated components
- The bottom receiving flask collects the lower boiling point component
- The receiving flask on the top collects the higher boiling point component
- The apparatus is used to purify liquids with different boiling points
