- 2 Erlenmeyer flasks
- 1 1-hole stopper that fits a flask
- 1 2-hole stopper that fits a flask
- some plastic tubing
- short lengths of glass tubing
- cold water bath (any container that can hold both cold water and a flask)
- boiling chip
- thermometer (optional)
Set Up the Distillation Apparatus
- The liquid you are distilling goes into one beaker, along with a boiling chip.
- This beaker sits on the hot plate, since this is the liquid you will be heating.
- Insert a short length of glass tubing into a stopper. Connect it to one end of a length of plastic tubing.
- Connect the other end of the plastic tubing to a short length of glass tubing inserted into the other stopper. The distilled fluid will pass through this tubing to the second flask.
- Insert a short length of glass tubing into the stopper for the second flask. It is open to the air to prevent pressure buildup inside the apparatus.
- Place the receiving flask in a large container filled with ice water. Vapor passing through the plastic tubing will condense immediately when it comes into contact with the cooler air of the receiving flask.
- It's a good idea to clamp down both flasks to help keep them from tipping over by accident.
