Soxhlet extractor

A schematic representation of a Soxhlet extractor:
  1. Stirrer bar
  2. Still pot (the still pot should not be overfilled and the volume of solvent in the still pot should be 3 to 4 times the volume of the Soxhlet chamber)
  3. Distillation path
  4. Thimble
  5. Solid
  6. Siphon top
  7. Siphon exit
  8. Expansion adapter
  9. Condenser
  10. Cooling water out
  11. Cooling water in

A Soxhlet extractor is a piece of laboratory apparatus[1] invented in 1879 by Franz von Soxhlet.[2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a 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.
