Columns |
| There are several types of fractionating column but the most common is the Vigreux column (1) which has indentations designed to force condensing liquid into the rising vapour. This is necessary to achieve the equilibrium needed for efficient fractionation. The Vigreux column is often incorporated into a still head (2). Alternative columns are packed with glass beads (3) or open columns (4). |
