Soxhlet extractor

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. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve a larger amount of material.
