  • Publication number: 20100144539
    Abstract: The present invention discloses an apparatus and method for rapid analysis of members of a combinatorial library. The apparatus includes a plurality of reactor vessels for containing individual library members, a fluid handling system that apportions a test fluid about equally between each of the vessels and a housing for enclosing the reactor vessels, the housing defining a pressure chamber, wherein the housing is configured to sustain a pressure substantially above atmospheric pressure. This allows for simultaneous screening of library members at high pressure by providing a small pressure differential on reactor components. The disclosed apparatus is especially useful for screening library members based on their ability to catalyze the conversion of fluid reactants.

  • Patent number: 7549978
    Abstract: A needle assembly has a first body and a guide rod supported for sliding movement between an extended position and a retracted position. A second body is attached to the guide rod. The second body is relatively farther from the first body when the guide rod is in the extended position and relatively closer to the first body when the guide rod is in the retracted position. The guide rod is biased to the extended position. The second body supports a venting needle that extends beyond the second body by a fixed length. A liquid handling needle is coupled to the first body. Sliding movement of the guide rod toward the retracted position retracts the second body and the venting needle relative to the liquid handling needle.
