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:
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 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.
Abstract:
A microbiological test array (12) with a generally flat base (11) having a plurality of upwardly projecting microwells (44) connected by a microchannel (42) to an open reservoir (50) formed in a top surface (13) generally parallel to the base (11) of the test array (12). The reservoir (50) has an opening to permit an inoculum-broth liquid solution to flow from the reservoir through the microchannel (51), to a sacrificial evaporation well (46) having an air vent port (48) adapted to control a vacuum filling process, and subsequently to be distributed into each of the plurality of microwells (44).
