颇尔 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
特色及优点
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
