The 3M Petrifilm E. coli/Coliform Count Plate is a sample-ready-culture-medium system which contains Violet Red Bile (VRB) nutrients, a cold-water-soluble gelling agent, an indicator of glucuronidase activity (BCIG), and a tetrazolium indicator that facilitates colony enumeration in food and beverage samples.

These plates provide both E. coli and total Coliform Count information with confirmed results in just 24-48 hours. By eliminating subsequent confirmation steps required with most traditional reference methods, the 3M Petrifilm E. coli/Coliform Count Plates can help increase productivity and reduce overall lab costs.

Three Easy Steps Offer Fast, Easy-to-Interpret Results:*

• 1) Inoculate - 3M Petrifilm E. coli/Coliform Count Plates are easy to inoculate. Lift the top film and add sample.
•  
• 2) Incubate - The space saving design minimizes incubator space requirements.
•  
• 3) Interpret** - Count the colonies. Confirmed coliforms are red or blue colonies with associated gas bubbles. Confirmed E. coli are blue colonies with associated gas bubbles. Results are fast and accurate.
•
