Batch Solid–Liquid Extraction (Soxhlet) Unit

Solid–liquid extraction is a semi-continuous process coupling distillation with a Soxhlet-type cartridge containing a solid impregnated with an active compound (solute) to be extracted by dissolution in a hot solvent.

The distillation column generates solvent vapours that are condensed; this pure, hot solvent feeds the cartridge containing the inert solid and solute. When the cartridge is full, the resulting solution drains automatically by siphoning and returns to the reboiler where the solvent is re-boiled.
