Patent ID: 7018589

Claim:
An apparatus for use in parallel reaction of materials, comprising: a base having a plurality of reaction wells formed in an upper surface of the base and extending partially therethrough, each of said reaction wells having a closed lower end defined by the base and an open upper end for receiving components for the reaction; a cover configured for sealing engagement with the base to form a housing enclosing said plurality of reaction wells and defining a common pressure chamber in communication with said plurality of reaction wells; an inlet port in communication with said pressure chamber for supplying pressurized fluid to said chamber to pressurize said plurality of reaction wells; and a flow restriction device positioned adjacent to said open ends of the reaction wells and comprising a plurality of flow passageways formed therein, each of said plurality of flow passageways configured to provide a direct fluid communication path between one of said plurality of reaction wells and said pressure chamber while reducing cross-talk between said plurality of reaction wells; wherein the material and structure of the pressure chamber is such that the chamber is operable to sustain an operating pressure of at least 30 psig.
