In the experiment introduced here, a mixture of water and methylated spirits made up by students themselves is to be separated into its components. The alcohol contained in the mixture will be distilled and collected in a conical flask. The simple distillation apparatus used here is made of nothing more than a distillation flask with a cooling jacket fitted to a nozzle in the neck and is highly suitable for introducing students to the basic principles of distillation.
