MULTI-CHAMBERED MODULE FOR USE INMONITORING GROWTH OF MICROORGANISMSAbstract of the DisclosureA multi-chambered module for holding separatesamples of nutrient media. A plurality of chambers, withaccess means into each, is permanently attached to anelectrically non-conductive base. Embedded within the baseunder the chambers is a plurality of electrically conductiveleads. Terminal portions at one end of the leads emerge inspaced pairs into each chamber forming electrodes therein.At the other end of the leads terminal portions are exposedfor contact with an electrical source. A signal passedthrough the electrodes in galvanic contact with media permitsthe impedance thereof to be determined, with changes ofimpedance directly associated with microorganism growththerein.
