Soxhlet extractor

A Soxhlet extractor is a kind of laboratory equipment.

However, a Soxhlet extractor is not limited to the extraction of lipids.

The Soxhlet extractor is placed onto a flask containing the extraction solvent.

Soxhlet extractor, which uses the same mechanism.

The Soxhlet extractor applies the solvent repeatedly to the solid until enough of the material dissolves.

Large-scale purifications employ a Soxhlet extractor.

Commercial samples are usually are contaminated with sulfur, which may be removed by washing with carbon disulfide in a Soxhlet extractor.

The process consists of the leaching of copper or its oxides with concentrated aqueous ammonia in a Soxhlet extractor.

He invented the Soxhlet extractor in 1879 and in 1886 he proposed pasteurization be applied to milk and other beverages.

Later, this instrument was modified by the German Franz von Soxhlet in 1879 to create the extractor that bears his name, Soxhlet extractor.

Normally a solid material containing some of the desired compound is placed inside a thimble made from thick filter paper, which is loaded into the main chamber of the Soxhlet extractor.

The thimble is surrounded by hot solvent vapour and maintained at a higher temperature compared to the Soxhlet extractor, thus allowing better extraction for compounds with higher melting points such as bitumen.

A minor use is in some types of Soxhlet extractor, where a concentric siphon is noted in advertising material as being more robust and having a lower volume than a U siphon.

Very similar to the Soxhlet extractor, the Kumagawa extractor has a specific design where the thimble holder/chamber is directly suspended inside the solvent flask (having a vertical large opening) above the boiling solvent.

It was apparently made by extracting and purifying THC from cannabis plant material using a soxhlet extractor, followed by reaction with acetic anhydride in an analogous manner to how heroin is made from morphine.
