Allihn condenser

The Allihn condenser or "bulb condenser" or simply "reflux condenser" is named after Felix Richard Allihn. The Allihn condenser consists of a long glass tube with a water jacket. A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense. Ideally suited for laboratory-scale refluxing.

To prevent the solvent from boiling away, a reflux condenser is used. This is a glass column with a second column surrounding it through which cool water flows. As vapor from the boiling solvent rises into inside column of the reflux condenser, it is cooled by the jacket of water on the outside and condenses.
