3M Petrifilm rapid coliform count plates available from 3M Food Safety (Microbiology) are designed to record presumptive coliform counts at 14 hours.  

This allows products to be released sooner with a higher level of confidence.    

Offering 24-hour result for both positives and negatives, 3M Petrifilm rapid coliform count plates eliminate the need for confirmation whereas, VRBA and MPN methods require confirmation that would take another 24 hours.  

3M Petrifilm rapid coliform count plates enable easy differentiation between coliforms and non-coliforms.  

The combination of acid zones and presence of gas easily identifies a colony as a coliform. The VRBA does not use gas as an indicator.  

Offering more precision than the MPN method, 3M Petrifilm rapid coliform count plates facilitate direct count that gives smaller confidence intervals.
