Soxhlet extractor Soxhlet extractor, also known as fat extractor or fat extractor, uses the principle of solvent reflux and siphon to continuously extract solid substances by pure solvent. The glass condenser tube of the Soxhlet extractor is cooled by a cooling water circulating machine, and the extraction liquid entering the condenser tube is condensed and recovered.

Soxhlet extractors do not require much pressure and flow. Generally, T1 or T2 series cooling water circulation machines are selected according to the evaporation capacity.
