PreFlow™Filter Capsules - Resin-Bonded Glass Fiber Filter

PreFlow resin-bonded glass fiber filter capsules have been designed for small volume production and scale-up evaluation.
Pall PreFlow media provide bioburden reduction, clarification, and prefiltration for sterilizing-grade filters when processing biological fluids. The fixed pore structure and proprietary resin-bonded glass fiber composite media provide exceptional capacity for fine contaminants and long service life.  

PreFlow filters have the following properties:

  • Fixed pore construction 
  • Resistant to contaminant unloading 
  • Meets USP Biological Reactivity Test, in vivo, for Class VI – 121 °C Plastics

Features and Benefits


The key benefits of DFA PreFlow capsules for prefiltration applications include: 
  • Scalablity to production filters 
  • Capsule format for ease of use 
  • Effective and reliable protection of final filters, including 0.2 µm and 0.1 µm sterilizing-grade — providing higher throughputs and longer filter life 
  • Low hold-up volumes 
  • High-strength design allows for multiple autoclave cycles 
  • Supplied with Certificate of Test giving batch traceability
