Air register openings provided within the rear table sink drain sheet adjacent the sump tank connect via a vertical tubular ducts, to an underlying main air tube subjected to low vacuum pressure for removing toxic vapors from the recessed sink during the performance of separation tests on coal submerged within liquid provided to the sump tank. A removable, elongated support shelf is mounted and extends across the rear of the sink recessed below said access opening from one lateral sloped wall portion to the other and overlies a part of the sump tank for resting beakers or the like thereon employed in the testing process.
