AELAB CN Gridded Membrane Filter for Microbiology Analysis FBM047CN Series

The AELAB CN Gridded Membrane Filter is a hydrophilic cellulose nitrate (CN) filter designed for accurate microbiological testing and colony counting. Gamma-irradiated for sterility and individually packed with easy-open separator paper, these membranes provide precision, convenience, and consistency in laboratory workflows. Available in both white and black options, they are ideal for a wide range of microbiology and quality control applications.

🔬 How It Works?

The CN Gridded Membrane Filter captures microorganisms on its microporous cellulose nitrate surface. The printed grid pattern ensures accurate colony counting and sample traceability. Its hydrophilic nature provides high flow rates for aqueous samples, while gamma irradiation guarantees sterility, making it ideal for sensitive microbiological analyses.
