Abstract:
A random access microbiological analyzer (10) for performing AST and ID tests on samples using on-board inventories of different AST test arrays (12) and different ID test rotors (16) within separate AST and ID incubation and analysis chambers (22, 28).
Abstract:
Performing antibiotic testing on samples contained in test arrays by orienting the arrays relative to the direction of gravity so that test solution within the microwells is drawn downwards and air within the microwells is forced to the uppermost portion of the test array. Antibiotic testing is conducted using an interrogating beam of radiation passing horizontally through the microwells at locations devoid of air bubbles.
Abstract:
A microbiological test array with a plurality of microwells connected by a microchannel to a solution reservoir. Subsequent to filling the microwells, the microchannels are sealed to protect the integrity of the solution in the test microwells.
Abstract:
A circular shaped rotor (16) to facilitate automated identification testing of microorganisms in a microbiology analyzer (10) having two circular arrays (120,124) of microwells downwardly projecting from the top of the rotor (16) connected to a recessed central region (114) by a plurality of microchannels (118,122) 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 (126) formed near its outer diameter.
