Gourt Home::Gourt :: Retort
In a chemistry laboratory, a retort is a glassware device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated. The neck acts as a condenser, allowing the evaporated vapors to condense and flow along the neck to a collection vessel placed underneath.
In industrial applications, a retort is an airtight vessel in which substances are heated for a chemical reaction producing gaseous products to be collected in a collection vessel or for further processing.
History
Retorts were widely used by alchemists, and images of retorts appear in many drawings and sketches of their laboratories. Before the advent of modern condensers, retorts were used by many prominent chemists, such as Antoine Lavoisier and Jöns Berzelius.
Role in analytical chemistry
In laboratory use, due to advances in technology, especially the invention of the Liebig condenser, retorts have largely been rendered obsolete. However, some laboratory techniques that involve simple distillation and do not require sophisticated apparatuses may use a retort as a substitute for more complex distillation equipment.
References in popular culture
In the Bethesda Softworks games Morrowind and Oblivion, retorts would evaporate and condense the arcane properties of alchemical ingredients. Alchemical potions created with a Retort would have higher positive effects, and have no change on the potency of damaging effects.
