Plate count agar (PCA) is a non-selective solid culture medium formulated to support the growth and enumeration of a broad range of aerobic microorganisms. PCA contains nutrient sources such as casein and yeast extract that provide amino acids, vitamins, and growth factors required for bacterial cultivation.

Also known as standard methods agar (SMA), PCA is widely used for total viable count assays, microbial enumeration, environmental monitoring, and routine quality control testing. Because of its broad growth support and reproducible performance, plate count agar is a foundational medium in food, dairy, and water testing, pharmaceutical quality control, and industrial microbiology workflows.

Our PCA plates are supplied as sterile, ready-to-use, pre-poured plates, eliminating the variability and preparation time associated with in-house media production. Each formulation is manufactured to precise specifications to ensure reliable microbial recovery and reproducible colony growth.

We manufacture our full catalog of PCA plates using validated processes and rigorous quality control standards to ensure sterility, performance, and lot-to-lot consistency. We also support custom manufacturing options, including alternative plate formats and specialized formulations to support specific microbial testing and quality assurance workflows.
