Abstract: A reaction vessel having a reaction chamber for holding a sample is fabricated by producing a housing having a rigid frame defining the minor walls of the chamber. The housing also defines a port for introducing fluid into the chamber. At least one sheet or film is attached to the rigid frame to form at least one major wall of the chamber. In preferred embodiments, two sheets or films are attached to opposite sides of the rigid frame to form two opposing major walls of the chamber, the major walls being connected to each other by the minor walls.

Abstract: Embodiments of the invention provide an efficient and effective technique for storing and dispensing reagent beads. In one embodiment, 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.

Abstract: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.
