ABSTRACT:
A plurality of disposable cartridges, each having a plurality of wells including at least one assay reaction well, are loaded in a plurality of openings arranged radially around a rack of a carousel. Securing of the cartridges in a predetermined orientation and position in said openings is ensured by means of alignment and securing means on the cartridges and corresponding means on the rack. A locking hub with tangs is mounted on the rack and is rotated to cause the tangs to contact locator tabs on each cartridge to force locator nubs on each of the cartridges radially into corresponding notches on the rack, and to accurately wedge the cartridges against the outer periphery of the rack. The carousel indexes for positioning the cartridges under a variety of stations, one of which generally contains an optical reader such as a fluorometer.
