3M® PetrifilmTM Plates
Each PetrifilmTM “plate” consists of two plastic film sheets with the sterile culture media in between . The sheets are separated briefly for inoculation with the material of your choice and then resealed and incubated . Growth occurs on the super thin film of media just like it does on the surface of an agar plate . You can stack a class set in the same space as one Petri dish . Results are visible through the clear film, and colonies are readily viewed . Transfers are possi- ble but not necessary . Disposal becomes easier . Once inoculated, the plates need never be opened again . Safe, easy, no preparation! Petrifilm can be kept for 18 months if refrigerated . Fifty plates take up as much space as one Petri dish . Ready to use with various media .
Petrifilm Aerobic Count Plates

Petrifilm Yeast and Mold Count Plates
An indicator dye stains yeast and mold colonies to provide contrast and facilitate counting .
Petrifilm E. coli/Coliform Count Plates
The coliforms produce red colonies . An additional indicator dye forms blue around E. coli colonies . Counting red and blue colonies yields the total coliform count .
