Use this apparatus for continuous extraction of analytes from a solid into an organic solvent. As the flask containing the solvent is heated, vapors rise in the larger outside tube, enter the water-cooled condenser, and liquate. When the liquid level in the extractor reaches the top of the bent tube, siphoning action returns the extract-enriched solvent to the flask. All wetted parts are manufactured from Wheaton 33 low extractable borosilicate glass that conforms to USP Type I and ASTM E-438 Type I, Class A requirements.
