Complete System Design. In addition to the extractor, an extremely important aspect of any extraction application is the design of the system to recover and recycle the solvent, and further purification of extracted products. In most cases, these additional steps are accomplished by means of distillation, and when necessary, are also studied during the pilot tests.

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 ...
