How Millipak® Barrier And Millidisk® Barrier Filters Streamline Final Sterile Filtration

In pharma and biopharma manufacturing, final sterile filtration is the focus of extensive regulatory interest. Regulatory guidelines recommend that critical filters used for the sterilization of liquids in aseptic processing should be flushed, preconditioned, integrity tested, and dried before product filtration.

Millipak® Barrier and Millidisk®  Barrier filters contain hydrophilic and hydrophobic sterilizing-grade Durapore® 0.22 μm membrane. As they allow the passage of both liquid and air, they can be used to simplify wetting and drying during integrity testing of sterilizing filters.
