Soxhlet Extraction - an overview ScienceDirect Topics

J. de Boer, in Encyclopedia of Analytical Science (Second Edition), 2005 Soxhlet Extraction. Soxhlet extraction is a simple and effective method. It has been used for a wide range of samples like soils, sediments, and animal and plant tissues. A wide variety of solvents like dichloromethane (DCM), pure or mixed with acetone or hexane, and acetone–hexane mixtures can be used.

SOXHLET EXTRACTION METHOD EPA 3540C

Soxhlet extraction uses relatively inexpensive glassware, once loaded requires no hands-on manipulation, provides efficient extraction, but is rather lengthy (16 to 20 hours) and uses fairly large volumes of solvent. It is considered a rugged extraction method because there are very few variables that can adversely affect extraction efficiency.

Soxhlet extractor - Wikipedia

A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. 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. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve a larger amount of material.
