3M™ Petrifilm™ High Sensitivity Coliform Count

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

Fast, Accurate, Results in 24 hours with three easy steps 

1) Inoculate – 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.   

Efficiency and convenience of Petrifilm Plates for 5 mL samples

One 3M™ Petrifilm™ High-Sensitivity Coliform Count Plate 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.  

This 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.  

A survey of 274 plants who converted to Petrifilm Plates from traditional agar methods found an average labor savings of 45% and an average increased technician efficiency of 80%. The end result is better process control, a higher quality product and an overall reduction in operational costs.
