Soxhlet Apparatus

Soxhlet Apparatus is a piece of laboratory apparatus and contain 250 ml of flask volume. It is originally designed for the extraction of a lipid from a solid material. It 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.
