Soxhlet ExtractionSoxhlet Extraction is a technique for the continuous extraction of analytes from a solid sample matrix. The apparatus consists of a piece of siphoning glassware attached to a flask containing the extraction solvent. A thimble containing the sample is placed in the extraction chamber of the siphoning glassware, and a condenser is attached on top of the apparatus. As the solvent is heated, the vapor travels to the condenser. The condensed vapor fills the extraction chamber until the level of solvent reaches the highest point of the siphon path. The solvent then drains back into the heating flask where it is redistilled and the extraction begins again.
- Low amount of solvent required
- Extract analytes quantitatively
- Determine percent crosslinking of polymers
