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 the 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 labour 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.
