ABSTRACT:
A concentrator/extractor apparatus for employing solvent to extract a substance from a sample in order to increase the concentration of the substance in less time than prior art apparatuses is disclosed. The disclosed apparatus, and kits including the disclosed apparatus and compatabile components, is provided with a sample containing body in which a hydrophobic membrane is utilized to prevent the sample liquid from migrating to the concentrator portion of the combination extractor/concentrator apparatus. Solvents having densities greater than, or lower than, the sample may be used to process such samples by the disclosed apparatus.
