Soxhlet extraction apparatus with standard taper ground joints is used for continuous extraction of analytes from a solid into an organic solvent.

• Manufactured from low extractable borosilicate glass

As the flask containing the solvent is heated, vapors rise in the larger outside tube, enter the water-cooled condenser and liquate and when the liquid level in the extractor reaches the top of the bent tube, siphoning action returns the extract-enriched solvent to the flask.
