The distillation column is used in chemical laboratories, breweries and oil refineries to separate a mixture of liquids into its individual components. 
The mixture (e.g. crude oil) is heated, the component that boils the easiest (e.g. kerosene) evaporates and leaves the mixture, passes through the column where it is cooled and condensed again in another recipient.

Separation in order to understand is at the heart of modern science and technology. It stands in opposition to bringing together in order to understand, which is at the heart of e.g. ecology (Cat. Nr. 13).
