Patent ID: 6890491

Claim:
A combinatorial chemical synthesis reaction tool, comprising: a plurality of reaction vessels adapted for chemical synthesis, a reaction vessel support disposed to hold the plurality of reaction vessels in a preferred orientation, a plurality of injection ports, each injection port including a pressure seal, situated to provide access to one of said reaction vessels, the plurality of injection ports operable for the injection of liquids into said reaction vessels, a plurality of evacuation ports, each evacuation port including a pressure seal, situated to provide access to one of said reaction vessels, the plurality of evacuation ports operable for the evacuation of fluids from said reaction vessels, and a plurality of injection fittings and evacuation fittings formed to matingly engage said respective injection and evacuation ports and to thereby enable the simultaneous delivery of fluids to the reaction vessels or the simultaneous evacuation of fluids from said reaction vessels, and an actuator for changing the relative orientations of the reaction vessel support and the plurality of injection fittings and evacuation fittings, so as to selectively align a given injection fitting and evacuation fitting with a different one of said reaction vessels.
