3M™ Petrifilm™ Coliform Count Plates provide a cost-effective, convenient and reliable method for testing equipment, raw materials, food products and manufacturing environmental samples. The 3M Petrifilm Coliform Count Plate is a sample-ready-culture-medium system which contains Violet Red Bile (VRB) nutrients, a cold-water-soluble gelling agent, and a tetrazolium indicator that facilitates colony enumeration in food and beverage samples.

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

Recommended Industry for Coliform Count Plates: Beverage & Bottled Water, Dairy, Eggs, Fruits & Vegetables, Meat, Nutraceuticals, Pet Food & Animal Feed, Poultry & Eggs, Prepared & Processed Foods, Seafood.
