Directly coated onto this base is a thin, uniform layer of gel that serves as the growth matrix. Its design is engineered to deliver results that are not only accurate but also highly reproducible, meeting the stringent requirements of regulatory compliance and HACCP plans.
Unlocking the Advantages of the Petrifilm Aerobic Count Plate
The petrifilm aerobic count plate emerges as a cornerstone technology in this landscape, offering a sophisticated yet straightforward method for quantifying viable aerobic bacteria in a wide array of samples. A precise volume of the test sample, whether it be a liquid, a pureed solid, or a diluted suspension, is then uniformly applied to the center of the film using a pipette or dispenser.
The critical step follows: using the provided spreading rod, the sample is carefully and evenly distributed across the entire counting area. This gel is composed of a nutrient-rich agar formulation specifically tailored to support the growth of aerobic mesophilic organisms, alongside a critical bottom layer of cold-water-soluble gelling agent.
Unlocking the Key Benefits of Petrifilm Aerobic Count Plates
The process begins with the rehydration of the film by opening the sachet and placing the petri film, grid-side up, on a clean surface. At its core is a stable polyester film base, which provides a rigid support and a defined counting area, typically marked with a grid for ease of enumeration.
