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. *Refer to instructions for use for additional information, and more details on validations.
