3M, St. Paul, , Minn., launched the 3M Petrifilm Aerobic Count Plate, a trusted, accurate and easy test that can detect aerobic bacteria counts in just 24 hours for most 3M Petrifilm platesfood matrices.

The 3M Petrifilm Rapid Aerobic Count Plate offers a faster time-to-result technology that reduces the impact of spreader colonies, and a simplified inoculation area to drive greater efficiency and reduce costly re-testing and delayed results. 3M Petrifilm Rapid Aerobic Count Plates also leverages a dual-sensing indicator technology for easy enumeration of colonies in raw material, in-process and finished product food testing as well as environmental air, swab or surface contact testing.

The sample-ready system uses an easy 3-step process—inoculation, incubation and enumeration. It contains nutrients, a cold water-soluble gelling agent and dual-sensing indicator technology that facilitates colony enumeration for most food matrices. Incubation temperatures are 32-35°C.
