Description

When low solubility or insoluble solids are to be extracted, then a Soxhlet extraction is carried out as in experiment C2.4.2.1. In this case the vapourised solvent condenses on a chiller and drips onto the extraction material in a filter sleeve. It collects in the extraction space, draws the extract out of the extraction material, and is automatically drawn into the flask. From there the solvent evaporates once again (without extract).
