3M™ Petrifilm® High-Sensitivity Coliform Count Plates

This allows a 1-coliform-per-gram sensitivity if a 1:5 dilution of product is made. A 2-coliform-per-gram sensitivity is achieved if a 1:10 dilution is used. Whether testing milk, ice cream, cheese, or other food products, testing labs can benefit from the labor savings of 3M Petrifilm Plates. These plates reduce overall testing costs and allow producers to easily conform to higher sensitivity standards.

3M Petrifilm High-Sensitivity Coliform Count plates may be especially well-suited for use in facilities producing dairy products, where regulations and strict internal quality standards demand a high-sensitivity test that can deliver results quickly and accurately.

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

1. Inoculate - 3M Petrifilm High Sensitivity 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. An indicator dye in the plate colors Gram-negative colonies red and the top film traps gas produced by the coliforms. Simply count red colonies that are associated with gas bubbles as coliforms.
