Each qualitative food microbiology proficiency test comes with five Snap-Stick™ inoculated swabs and five 4” x 4” sterile square petri dishes. To activate the microorganism, simply apply pressure to the plastic stem valve and release the hydration fluid to dissolve the microorganism pellet. The culture pellet lyophilized in Microgel-Flash™ matrix dissolves in less than a minute with minimum agitation and no incubation. Once dissolved, remove the swab from the tube and swipe across the square petri dish base. At least 2 of 5 samples swabs will test positive for the target microorganism; acceptable evaluation requires at least 4 of 5 recorded correctly with no false negatives.
