Two results on one convenient plate

E.Coli Coliform plate with incubation time

3M Petrifilm E.coli / Coliform Count plates provide a count for both E.coli and Total Coliforms with confirmed results available within 24-48hrs. The plates are supplied as a ready-to-use medium system which contains Violet Red Bile (VRB) nutrients, a cold-water soluble gelling agent, an indicator of glucoronidase activity (BCIG) and a tetrazolium indicator that facilitates colony enumeration in food and beverage samples. 

Count blue to red/blue colonies associated with entrapped gas, regardless of size or intensity of colour, as confirmed E.coli. Other Coliform colonies are red and closely assciated (within one colony diameter) with entrapped gas. Colonies not associated with gas (a distance greater than one colony diameter between colony and gas bubble) are not counted as coliforms. 

Total coliform count consists of both red & blue colonies associated with gas at 24 hours. Anytime within the validated method incuabtion period that a blue clony associated with gas appears, it is confirmed as E.coli.

The 3M Petrifilm E.coli / Coliform Count Plate can also be read using the 3M Petrifilm Plate Reader which provides consistent, fast automated readings and recording of results in 4 seconds.
