The 3M™ Petrifilm™ Plates Raising efficiency, productivity and safety standards - Unique technology for ready to use microbiological testing - Pluses in your laboratory which will convince you
The enumeration of coliforms (total or thermotolerant). A reading facilitated by an indicator which colours colonies red. The upper film traps the gas produced by lactose fermentation.
Two tests in one: enumeration of Escherichia coli and coliforms. It contains a ß-glucuronidase indicator for detection of E.coli. Resulsts in 24 or 48 hours.
- Enumeration of Enterobacteriaceae - Acid production by colonies, highlighted through a pH indicator which turns yellow - Upper film traps the gas produced by glucose fermentation
- Enumeration of small numbers of coliforms (less than 1 or 2 per gram) - Inoculation of 5ml of sample or dilution of it - Reading advantages (colour and gas) identical to those for 3M Petrifilm Coliform Count Plates
- Rapid enumeration of coliforms - Very sensitive pH indicator reveals production of acid by growing colonies - Growth acceleration reduces the response time (14 hours versus 24 hours)
