Liebig condensing column
Liebig condensing column
- Description (Brief)
- This Liebig condenser was made by Whitall Tatum Company. A Liebig condenser is used to cool and condense a gas back to a liquid, often as part of the process of chemical distillation. The piece consists of a straight glass tube through which the gas travels. A water jacket surrounds the tube and helps to cool the gas.
- The form is now associated with renowned German chemist Justus von Liebig (1803–1873), who suggested improvements for the condenser in 1843. However, German chemist Christian Ehrenfried Weigel (1748–1831) first mentioned the form in 1771. Historian of chemistry William B. Jensen suggests that Liebig’s name became associated with the condenser due to the many students who first encountered the form in his laboratory.
- Whitall Tatum Company was among the first American glass companies to manufacture chemical glassware, starting as early as the late 1870s. Based in Millville, New Jersey, the company’s factory produced chemical and other glassware for over 150 years, finally closing its doors in 1999.
- Whitall Tatum donated this object to the Museum in 1921, at the request of Charles Whitebread, assistant curator in the Division of Medicine. Whitebread planned to use the object as a part of an exhibit to illustrate pharmaceutical methods used in the manufacture of medicine. He hoped to “illustrate some of the operations to which crude drugs are subjected to get them into a form suitable for administration.” The methods he planned to display included: vaporization, distillation, sublimation, comminution, desiccation, sifting, levigation, precipitation, dialysis, expression, percolation, solution, lotion or displacement washing, decantation, collation or straining, filtration, and separation of immiscible liquids.
