3M™ Petrifilm™ High-Sensitivity Coliform Count Plate


By accommodating a 5mL sample, the 3M™ Petrifilm™ High-Sensitivity Coliform Count Plate allows for the detection of low levels of coliforms in 24 hours.

The 3M™ Petrifilm™ High Sensitivity Coliform Count Plate is especially suitable for use in facilities producing dairy products where federal and state regulations, along with strict internal quality standards, demand a high-sensitivity test that can deliver results quickly and accurately. Fast, Accurate, Results in 24 hours with three easy steps:


1) Inoculate - 3M™ Petrifilm™ Plates are easy to inoculate. Lift the top film and add sample 
2) Incubate - The space saving design maximizes incubator space and 
3) Enumerate - Count red colonies that are associated with gas bubbles as confirmed coliforms. A built in grid facilitates counting colonies, giving fast, precise and accurate results.


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.
