Abstract
A toxic substance extraction cell includes a chamber for housing a heated solvent, a pair of gaskets adapted to be seated on the solvent housing between which is clamped a specimen to be tested; the space between the gaskets being liquid tight, and a cover for clamping the gaskets to the solvent housing. After assembly of the cell with the preheated solvent in the housing and the specimen to be tested between the gaskets, the cell is inverted and supported on a plurality of legs provided on the cover. The solvent is thus placed in contact with the specimen in order to dissolve any toxic substances contained within the specimen. The cell is then reinverted and supported on a suitable stand and allowed to cool, disassembled, and the solvent removed and tested for toxic residue.
