In order to produce a sterile filtrate for chemical, cell-based or plasma products, the location and type of filter is imperative. Critical Process Filtration sterilizing solutions remove biological contaminants from products before packaging and have an effective pore size of 0.22µm or 0.20µm and below. These membrane filters are integrity tested and validated to ASTM F838 for ≥ 7 log reduction of bacteria. Choosing the right filters not only protects product integrity, patients and brand, but will impact overall process efficiency.
