  • Publication number: 20110171748
    Abstract: Various embodiments described in the application relate to an apparatus, system, and method for generating, within a conduit, discrete volumes of one or more fluids that are immiscible with a second fluid. The discrete volumes can be used for biochemical or molecular biology procedures involving small volumes, for example, microliter-sized volumes, nanoliter-sized volumes, or smaller. The system can comprise an apparatus comprising at least one conduit operatively connected to one or more pumps for providing discrete volumes separated from one another by a fluid that is immiscible with the fluid(s) of the discrete volumes, for example, aqueous immiscible-fluid-discrete volumes separated by an oil.

  • Patent number: 6123336
    Abstract: A sealing device (20) includes a layer of sealant (22) for sealing an internal surface (30) of a hollow member (34). The internal surface is nonparallel to the open end of the hollow member, and has an aperture pattern (44) for receiving at least one substrate (40) extending from a support surface across the hollow member. The layer of sealant is disposed adjacent the internal surface and supported by a backing (24) having an aperture pattern corresponding to the aperture pattern of the internal surface. The backing is spaced from the support surface and is movably supported inside the hollow member. The layer of sealant is adhered to the front surface of the backing to form a self-supporting article that can be easily positioned into the hollow member. One or more substrates can be inserted through the support surface across the hollow member, through the apertures in the backing and the layer of sealant, and through the apertures on the internal surface.
