Abstract: A rinsing and drying apparatus of a clinical analyzer probe drain station is provided. The rinsing and drying apparatus has a group of nozzles that are offset from a longitudinal axis of a probe passage and may be inclined and oriented to provide tangentially oriented fluid-jet trajectories exiting into the sample probe passage. The offset nozzles, nozzle orientation, and cavity geometrical features of the device permit the drying capacity of probe-impinging planar air-knife jets to be maximized by stabilizing local internal fluid movement to form a swirling (e.g., helical) gas flow field directed away from a drying region and toward a vacuum exhaust. The rinsing and drying apparatus eliminates rinse water re-circulated entrainment and up-wash (spitting) during the air-knife drying operation. Therefore, the rinsing and drying apparatus significantly reduces water carryout on sampling probes thereby reducing sample/reagent dilution.

Abstract: A lidstock for a open sample container having a plurality of slits to form segment intersections that facilitate penetration by an aspiration probe, the segment intersections displaced from the location for penetration by the probe.

Abstract: A circular shaped rotor to facilitate automated identification testing of microorganisms in a microbiology analyzer having two circular arrays of microwells downwardly projecting from the top of the rotor connected to a recessed central region by a plurality of microchannels formed in the upper surface and connecting the recessed central portion to the second plurality of microwells; the rotor is further adapted to be rotated by a source of rotational energy and moved throughout the analyzer using troughs formed near its outer diameter.
