How to Use Petrifilm Plates

Petrifilm Plates are ready-to-use food safety tests with three simple steps; innoculate, incubate, and interpret. To get started, open the Petrifilm Plate package, remove a plate, and dispense the sample onto the center of the plate. Use the Petrfilm Plate spreader to ensure uniform coverage of the sample. Next, place the Petrifilm Plates in an incubator. After incubation, begin counting colonies manually or with the Petrfilm Plate Reader Advanced. Always read and follow the Petrifilm Plate instructions for specific step-by-step procedures.
