Abstract:
A test device adapted to facilitate automated identification testing of microorganisms in a microbiology analyzer, the test device comprising:a circular rotor with opposed top and bottom surfaces, said rotor having a central axis, a diameter, a generally vertical radial sidewall connecting the top and bottom surfaces at the diameter of the rotor, and having a central portion recessed below the top surface; a first plurality of downwardly projecting microwells formed in the upper surface and distributed equidistant from one another in a first circular array located at a first distance from the central axis; a second plurality of downwardly projecting microwells formed in the upper surface and distributed equidistant from one another in a second circular array, located at a second distance from the central axis, the second distance being smaller than the first distance; a first plurality of downwardly projecting microchannels formed in the upper surface and connecting the recessed central portion to the first plurality of microwells; a second plurality of downwardly projecting microchannels formed in the upper surface and connecting the recessed central portion to the second plurality of microwells; wherein the rotor is adapted to be rotated by a source of rotational energy.
