A Soxhlet extractor is a piece of laboratory apparatus [1] invented in 1879 by Franz von Soxhlet. [2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent , and the impurity is insoluble in that solvent.
Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...
Accelerated solvent extraction (ASE), also known as pressurized solvent extraction (PSE), is a method for extracting various chemicals from a complex solid or semisolid sample matrix. The process uses high temperature and pressure, which results in the extraction taking less time and requiring less solvent, and possibly also giving better ...
Soxhlet extractor. Franz von Soxhlet was born on 12 January 1848 in Brno, Moravia, Austrian Empire and migrated with his family to the German Confederation.He was the son of spinning industrialist Hubert Soxhlet, an immigrant from Dalhem near Liège (in the former Duchy of Brabant).

Extraction Profile for Different Types of Extraction. The extraction curve of % recovery against time can be used to elucidate the type of extraction occurring. Figure 4(a) shows a typical diffusion controlled curve. The extraction is initially rapid, until the concentration at the surface drops to zero, and the rate then becomes much slower.
A new federal report shows that one drink per day is associated with negative health effects like liver cirrhosis and cancer, while a recent report from the surgeon general highlighted cancer ...
I have added redirects to Soxhlet extractor in all cases. --Quantockgoblin 14:34, 5 December 2006 (UTC) More classical set up would never use a straight condenser because so much heat is applied to the pot - usually a friedrich (sp?, pic below) or similar with a more tortuous path to more efficiently condense the hot vapor.
