PreFlow™ Cartridges

Pall PreFlow filters have been expressly designed to bring a significant improvement to prefiltration technology. The filter media utilized is based on our expertise in manufacturing rugged resin-bonded glass fiber composites. These sanitary-style filter cartridges are manufactured with pleated high-area construction for long service life. PreFlow filters are designed to reduce costs and are especially suited for biological prefiltration applications, including serum, vaccines, tissue culture media, and protein solutions.

Features and Benefits


  • Unparalleled protection of final membrane filtersFixed pore construction
  • No unloading or media migration
  • High-capacity for economy
  • High-strength design
  • A choice of particulate removal efficiencies
  • Autoclavable and steamable
  • Manufactured for use in conformance with cGMP
  • ISO 9000 Certified Quality System

Note: These filters are also available in Kleenpak Nova capsule format.

Quality and Bio-Safety


Biological Tests


  • Meets USP Biological Reactivity Test, in vivo, for Class VI-121° C Plastics

Effluent Quality Tests*


  • Non-Pyrogenic per USP Bacterial Endotoxins (< 0.25 EU/mL)
  • Meets Total Organic Carbon and Water Conductivity per USP Purified Water; pH per Sterile Purified Water
    * Per lot soak or rinse-up flush aliquots.
