Soxhlet Apparatus, Working Principle, Uses and Applications
What is a Soxhlet Apparatus?
A Soxhlet extractor is an extraction equipment utilized for continuous solvent extraction from solid samples in a laboratory. The Soxhlet extractor is mostly used where the substance of interest is slightly soluble in the solvent and where the impurities are insoluble.
It helps in extracting multiple times without having to replace the solvent. It is very effective in fat extraction, oil determination, chemical extraction, and analytical purposes.
Samples extracted using a Soxhlet apparatus include:
Food samples
- Oil seeds
- Soil
- Polymers
- Bio-fuel samples
- Pharmaceuticals
- Agricultural samples
Soxhlet Apparatus Principle
Soxhlet extractor extraction principle is achieved through a series of steps that include evaporation, condensation, and siphoning.
The process occurs as follows:
- Heating of the solvent in the boiling flask
- Vaporization of the solvent to the condenser
- Cooling and condensation of the vapor to form the solvent
- Dripping of the solvent to the sample in the thimble
- Filling up of the chamber by the solvent mixed with the extract
- Solvent flows back to the flask once it reaches the siphon level.
This process continues until the extraction is completed.
Soxhlet Apparatus Parts
The components of a typical Soxhlet apparatus include the following:
- Boiling flask
- Extraction flask
- Thimble holder
- Extraction thimble
- Siphon tube
- Condenser
- Heat source
- Supporting stand and clamps
This set-up works to achieve efficient solvent extraction.
Soxhlet Apparatus Uses
Applications of the Soxhlet apparatus are vast and indispensable in many industries.
Some applications are:
- Extraction of fat from food samples
- Oil determination
