<p>Au automated analytical instrument for conducting assays for components of interest in fluid samples. The instrument includes a rotatably mounted supply unit or segment (107) adapted to hold a plurality of foil-sealed magazines (109) containing assay modules (19), a testing system for assaying a fluid sample for a component of interest using an assay module, an assay module transport assembly (23) for transporting an assay module (19) from a magazine (109) in the supply unit to the testing system, and a microprocessor for controlling the operation of the automated analytical instrument. In one embodiment, the assay module transport assembly (23) includes a cutter assembly (171) for cutting away a layer of material such as a thin foil layer (127-1) covering a desired assay module (19) within the magazine (109), an assay module receiving platform (161) disposed in front of the magazine (109), an assay module ejector mechanism (151) for pushing an assay module (19) from the magazine (109) onto the assay module receiving platform (161), and an assay module transfer mechanism (173) for moving the assay module (19) from the assay module receiving platform (161) to the testing system. The cutter assembly (171) and the assay module receiving platform (161) are movable vertically on a first elevator assembly, and the assay module ejector assembly is movable vertically on a second elevator assembly.</p> |
