Patent number: 5714127Abstract: A system for the multiple, simultaneous synthesis of compounds preferably uses a reaction apparatus comprising a reservoir rack having a plurality of reaction wells, a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends, a holder block, having a plurality of apertures, and a manifold, which has ports to allow introduction/maintenance of a controlled environment. The manifold top wall has a plurality of apertures in axial alignment with the reaction tubes and a gasket which allows penetration by a needle in order to dispense and aspirate materials from the reaction tubes. Sealing members, such as gaskets, are placed between the holder block, manifold and reservoir rack and the components are releasably fastened together. A robotic sample processor is used to automate the synthesis process using the reaction apparatus.Type: GrantFiled: June 7, 1995Date of Patent: February 3, 1998Assignee: Warner-Lambert CompanyInventors: Sheila H. H. DeWitt, John S. Kiely, Michael R. Pavia, Mel C. Schroeder, Charles J. Stankovic

Patent number: 5702672Abstract: An apparatus for multiple, simultaneous synthesis of compounds which consists of: a reservoir block having a plurality of wells; a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends; a holder block, having a plurality of apertures; and a manifold, which may have ports to allow introduction/maintenance of a controlled environment. The manifold top wall has apertures and a detachable plate with identical apertures. The apparatus is constructed from materials which will accommodate heating, cooling, agitation, or corrosive reagents. Gaskets are placed between the components. Rods or clamps are provided for fastening the components together. Apparatus operation involves placing the filters on the lower ends of the reaction tubes in the reservoir block wells, and the upper ends passing through the holder block apertures and into the manifold.Type: GrantFiled: October 10, 1995Date of Patent: December 30, 1997Assignee: Warner-Lambert CompanyInventors: Sheila H.
