3M Petrifilm™ Aerobic Count (AC) Plates

The 3M™ Petrifilm™ Aerobic Count Plate is a time-saving, sample-ready plate designed to determine total aerobic bacteria populations. 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.

The 3M Petrifilm Aerobic Count Plate provides total aerobic count in as little as 48 hours. A red indicator dye in the plate colours 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. In addition, 3M Petrifilm Aerobic Count Plates can be used to aerobically or anaerobically enumerate lactic acid bacteria in food and environmental samples.

Recommended Industries for Aerobic Count Plates: Bakery, Beverage & Bottled Water, Chemicals, Confectionary, Dairy, Eggs, Fruits & Vegetables, Grain & Oilseed Milling Sector, Meat, Nutraceuticals, Nuts, Pet Food & Animal Feed, Poultry, Prepared & Processed Foods, Seafood

3M Petrifilm Rapid Aerobic Count Plates are fast, accurate, sample-ready culture medium systems. They contain nutrients, a cold-water-soluble gelling agent, and a dual-sensing indicator technology that allows you to easily count colonies in just 24 hours for most food matrices. Faster results and less labour mean more time and resources for monitoring your processes, ensuring tighter process control and improving product quality.
