Soxhlet Extraction – Principle, Working, Uses With Diagrams

Dec 24, 2021  Soxhlet extraction is a modern extraction technique in which we circulate the same solvent through the extractor several times. It is a type of continuous extraction technique but we can call it a series of short maceration. Soxhlet extractor needs the desired compound to be soluble in the solvent at a high temperature.

Soxhlet Extraction - an overview ScienceDirect Topics

The Soxhlet extraction is a combination of both, percolation and maceration methods. The extraction is carried out in a special apparatus known as Soxhlet apparatus that was designed by Franz von Soxhlet in 1879 [4]. It has been one of the most widely used extraction method which is still used extensively.
