LIEBIG'S CONDENSER
c.1850
Lacquered brass. Unsigned and undated. A contemporary account read: "In the laboratory various modifications of condenser are employed. The most convenient form of apparatus is that known as Liebig's. It consists of an outer metallic tube, through the axis of which a glass tube is passed, and is supported by perforated corks: the space between the two tubes is filled with water, which is continually renewed by cold water which enters by a funnel near the lower extremity, while the hot water escapes at the other end. The method of using it is sufficiently indicated in fig. 109." W. A. Miller, Elements of Chemistry: Theoretical and Practical, Part I: "Chemical Physics" (London 1855), pp. 236-37.
