Unlike traditional agar methods, 3M™ Petrifilm™ Plates are ready to use — no preparation required. Each slim pack offers consistent, uniform testing media. Just open it up and get right to work. Free up time and work more efficiently, without sacrificing quality or accuracy.
Heating, stirring, pouring, waiting … who’s got time for that?
It’s time to ditch the painful agar preparation stage. 3M Petrifilm gives you a wide choice of indicator organism testing plates that are ready to go, right out of the pack. They require less energy and water than traditional methods. And the flat, compact design uses less storage than bulky plates.
3M Petrifilm Plates are designed to save you time, effort and space! These ready to use, alternatives to agar require no preparation and their compact size means they take up less storage and incubator space. Plus, when combined with the 3M™ Petrifilm™ Plate Reader Advanced, you can increase capacity with minimum effort with accurate plate counts in just 6 seconds or less.
Results you can trust.
3M Petrifilm Plates allow you to standardise your testing and they are easy to use, supporting consistent use between technicians. That means accurate, repeatable results, time after time. And the peace of mind for you.
3M Petrifilm Plates have been internationally recognised and validated for their methods and innovation. Third-party validations confirm that the method has been scrutinised to prove that it is reliable, repeatable and has performed equal to or better than the reference method to which it was compared.
Sustainability is an increasingly important goal for companies all over the world and 3M has solutions that can help companies meet sustainability targets whilst supporting their business goals. A prime example is 3M Petrifilm plates that help customers reduce waste, cut greenhouse gas emissions, save energy and consume less water, while helping to streamline, standardise and simplify microbial indicator testing.
The long-term financial success of your company is ultimately built on the productivity and efficiency of your processes and employees.
With significant productivity and performance advantages over traditional agar plates, it’s no wonder that 3M Petrifilm Plates have become a standard method in microbial indicator testing for companies all over the world.
Switching from agar to 3M Petrifilm count plates can reduce labour costs spent on this testing process by an average of 45%, allowing your team to focus their time on other activities.
A 3M study conducted with 292 food plants demonstrated an 80% increase in technician productivity (tests per hour) saving companies an average of 3.7 hours per day of technician time.
With some 3M Petrifilm count plates delivering results in up to half the time of traditional agar methods, plus, with the time saved not having to prepare agar, you can keep your food products moving and avoid unnecessary hold time.
Shelf-stable and nearly as thin as paper, 3M Petrifilm count plates take up to 85% less of your valuable counter and storage space.

Are you still using agar dishes for microbial indicator testing? If so, you’re missing a big opportunity to not only boost your lab’s productivity and accuracy, but also help meet your company’s sustainability goals. 3M Petrifilm Plates can reduce your environmental impact over using agar plates in four key areas:
Every day, food processors, retailers and consumers are forced to throw out food due to microbial spoilage. This not only contributes to food waste and costly recalls, but can also damage a company’s brand reputation. Learn about food spoilage in the food and beverage industries with a new educational series by 3M Food Safety and food spoilage expert Dr. Randy Worobo of Cornell University.
Dr. Worobo is a Professor of Food Microbiology at Cornell University. He is responsible for teaching undergraduate and graduate food safety assurance classes, and his research is focused on non-thermal processing alternatives for juice and beverages, microbial spoilage of foods and beverages, pathogen transmission and survival on fruits and vegetables.
3M Petrifilm Plates are a convenient and reliable way to detect environmental microbial contamination. The construction of 3M Petrifilm Plates allows them to be used for direct contact or swab contact monitoring procedures, as well as air sampling procedures.
Your comprehensive resource for environmental monitoring in the food and beverage industries. For expert advice on building and enhancing your environmental monitoring program, including a chapter about indicator testing, explore our free Environmental Monitoring Handbook.
Effective environmental monitoring programs (EMPs) rely on hygiene monitoring as an integral component. A robust hygiene monitoring program that utilizes both ATP testing and microbiological testing can help food manufacturers meet regulations, assess the effectiveness of their cleaning and sanitation operations, and support food safety and quality.
