ABSTRACT:
A device to facilitate the use of extraction discs used in analysis of water impurities includes a cylindrical body with a top cavity to receive the extraction disc with a threaded ring holder to hold an open bottom container sealed on the extraction disc with a valve to selectively channel flow from the extraction disc into three downward passages, two of which open through the bottom into wash and elute sample containers and a third to a tube that opens into a large collection container sealably attached to the bottom of the body around the smaller containers with a vacuum passage through the bottom of the body into the large container controlled by a valve. The body has two parallel slots on opposite sides of the body to engage into cut outs of a rack panel supported above a housing with a slanted top wall with elliptical holes cut to receive the collection container and support it sticking out of the housing.
