Microbiological testing is mainly used for quality control in the pharmaceutical, cosmetics, municipal water supply, disease control, and food and beverage industries.


Membrane filtration is the conventional preferred method for microbial limit testing/bioburden testing. Trap microorganisms from the liquid by a specific membrane filter, then place them on a culture medium. The microorganisms will grow into colonies on the membrane surface for culturing, counting and identifying.


Cobetter provide microbial limit testing products based on membrane filtration, including sterile gridded membrane filters, disposable filter units and stainless steel manifold, to ensure safety and regulatory compliance.

  • Inhibitive substance can be rinsed off
