The 3M™ Petrifilm™ High-Sensitivity Coliform Count (HSCC) Plate is a sample-ready-culture medium system which contains modified Violet Red Bile (VRB) nutrients, a cold-water-soluble gelling agent, and a tetrazolium indicator that facilitates colony enumeration. 3M Petrifilm HSCC Plates are used for the enumeration of low levels of coliforms in the food and beverage industries. A 5 mL sample is plated onto one plate. This allows a 1-coliformper-gram sensitivity if a 1:5 dilution of product made. A 2-coliform-per-gram sensitivity is achieved if a 1:10 dilution is used.

Details

The 3M™ Petrifilm™ High-Sensitivity Coliform Count Plate accommodates 5 mL samples and detection of low levels of confirmed coliforms in 24 hours.

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.

Benefits
3M™ Petrifilm™ High Sensitivity Count Plates are sample-ready to use at any time to streamline your testing process. One 3M Petrifilm High-Sensitivity Coliform Count Plate, at a 1:5 dilution, takes the place of three standard pour plates for 1 CFU/gram testing. This will reduce your overall cost per test while easily conforming to higher sensitivity standards. The indicator dye and built in grid allows fast accurate identification of colonies.
