• Principles of Filtration
  pore size may pass through the membrane or may be captured within the membrane by other mechanisms. Membrane filters are typically used for critical applications such as sterilizing and final filtration. (Example: Supor and GN-6 Metricel membranes). Advantages: Absolute sub-micron pore size ratings...
