short-path distillation Kugelrohr distillation CHMO:0002114 https://orcid.org/0000-0001-5985-7429 2009-07-06T01:47:30Z A method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. As the sample mixture to be purified is heated, its vapours rise a short distance into a vertical condenser (called a 'Kugelrohr') where they are cooled by water. This technique is used for small amounts of samples with high boiling points (usually >300 °C) under greatly reduced pressure.
