[origin: US5209766A] A laboratory gas scrubber for removing soluble contaminant gases from the exit air from laboratory extractor hoods comprises a cabinet which is assigned to a laboratory extractor hood and is placed close beside the latter to form a closed subassembly and which contains in its lower part a scrubbing liquid tank, an immersion pump immersed in the latter, and a switchbox with the electrical control devices for operating the laboratory gas scrubber, while its upper part contains an inner housing with inlet connectors for the exit air which is emerging from the laboratory extractor hood and is to be purified, and an outlet connector for the purified exit air, and this inner housing contains a packing zone, above this a spraying zone and above this an agglomeration zone. It is possible for two or three laboratory extractor hoods to be arranged beside the laboratory gas scrubber and to be connected to the latter.
