ABSTRACT:
An automated micro-organism culture growth and detection apparatus includes a plurality of carousel trays arranged in pairs, providing receptacles for a plurality of culture bottles. The bottles each include a pair of electrodes submerged in the culture liquid and extend through an end wall of the bottle to form contact points. The receptacles include a pair of spring finger electrical contacts for each bottle to connect the electrodes to a measuring circuit. The complementary sets of the pairs of carousel trays are driven in counter-rotational directions to provide agitation for the culture during incubation and to index the individual to an access door in the incubation chamber surrounding the assembled carousel trays. A continuous flow of air at a controlled temperature is caused to flow through the incubation chamber which, together with the agitation, promotes the rapid growth of micro-organism in the culture bottles. The operation of the entire system including the driving of the carousel trays and the measuring of the growth characteristics of the micro-organisms is under the control of a micro-computer.
