  • Patent number: 9789481
    Abstract: The present invention provides a cartridge for analyzing a fluid sample. The cartridge provides for the efficient separation of cells or viruses in the sample from the remaining sample fluid, lysis of the cells or viruses to release the analyte (e.g., nucleic acid) therefrom, and optionally chemical reaction and/or detection of the analyte. The cartridge is useful in a variety of diagnostic, life science research, environmental, or forensic applications for determining the presence or absence of one or more analytes in a sample.

  • Publication number: 20170252742
    Abstract: A fluid control and processing system for controlling fluid flow among a plurality of chambers comprises a body including a fluid processing region continuously coupled fluidicly with a fluid displacement region. The fluid displacement region is depressurizable to draw fluid into the fluid displacement region and pressurizable to expel fluid from the fluid displacement region. The body includes at least one external port. The fluid processing region is fluidicly coupled with the at least one external port. The fluid displacement region is fluidicly coupled with at least one external port of the body. The body is adjustable with respect to the plurality of chambers to place the at least one external port selectively in fluidic communication with the plurality of chambers.

  • Publication number: 20160367991
    Abstract: A cartridge for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.

  • Patent number: 9446409
    Abstract: Embodiments of the invention provide an efficient and effective technique for storing and dispensing reagent beads. In some embodiments, an apparatus is provided for dispensing reagent beads contained in a bead storage device which includes a bead carrier having a plurality of wells; a plurality of reagent beads disposed in the wells; and a cover tape releasably attached to the bead carrier to cover the wells and retain the reagent beads in the wells. The apparatus comprises a channel in which to place the bead storage device with the bead carrier facing a support wall of the channel and the cover tape facing a stripping wall of the channel. The stripping wall includes a stripping gap disposed between a stripping edge and an opposite edge, and a dispense opening provided adjacent the opposite edge on a side of the stripping wall opposite from the stripping edge.
