ABSTRACT:
An apparatus and process for detecting and enumerating specific microorganisms from large volume samples containing small numbers of the microorganisms wherein the large volume samples are filtered through a membrane filter 23 to concentrate the microorganisms and filter 23 is positioned between two absorbent pads 21 and 25 previously moistened with a growth medium for the microorganisms. A pair of electrodes 13 and 15 are disposed against filter 23 and the pad-electrode-filter assembly retained within a petri dish 17 by retainer ring 27. Cover 29 is positioned on base 19 of petri dish 17 and sealed at the edges thereof by a parafilm seal prior to being electrically connected via connectors 14 and 16 to strip chart recorder 11 for detecting and enumerating the microorganisms collected on filter 23.
