What is Soxhlet Extractor?

Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve a larger amount of material. A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the thimble.

Features of Soxhlet Extractor

  1. DW-SXT-06/DW-SXT-02 Soxhlet extractor takes use of Soxhlet extraction and weight determination method to analyze fat content, that is, dissolve fat with an organic solvent, then extract fat from the solvent, dry it and weigh, finally calculate the fat content.
  2. DW-SXT-06/DW-SXT-02 Soxhlet extractor is mainly by the heating extraction, solvent recovery, and cooling of the three major components. The soxhlet extractor can be operated according to the boiling point of the reagent and the ambient temperature to adjust the heating temperature, the sample in the extraction process is repeatedly soaked and extracted, so as to achieve rapid extraction purposes; The soxhlet extraction can automatically recover the solvent, greatly facilitate the use of the user, and save a lot of time.

Application Areas

The soxhlet extractor design is reasonable, stable performance, high precision, labor-saving, time-saving, extraction methods in line with national standards, the indicators and performance of imports of similar products are required. The soxhlet extractor is the ideal equipment for Soxhlet extraction in food, grease, feed and other industries.
