3M™ Petrifilm™ Aerobic Count Plates are sample-ready and can help determine aerobic bacteria populations in testing processes. The indicator dye and built-in grid allows for fast accurate identification of colonies.
The 3M Petrifilm Aerobic Count Plate provides total aerobic count in as little as 48 hours. A red indicator dye in the plate colors all colonies red for better contrast and easier colony counting. The red colonies are also easily distinguished from opaque food particles that can cause confusion when using other plating methods. A built in grid facilitates counting colonies, helping to provide fast, precise and consistent results. Each 3M Petrifilm Aerobic Count Plate contains a water soluble gelling agent, nutrients and indicator — all the components needed for microbial growth with no agar preparation required. In addition, 3M Petrifilm Aerobic Count Plates can be used to aerobically or anaerobically enumerate lactic acid bacteria in food and environmental samples. The 3M Petrifilm Aerobic Count Plate can also be read using the 3M Petrifilm Plate Reader which provides consistent, fast, automated reading and recording of results in 4 seconds.
