High-Performance PP Clarification Filters

High-Performance PP Clarification Filters

Polypropylene (PP) membrane is suitable for depth filtration with stable physical and chemical properties and strong pressure resistance. Alioth prefilters are made of PP with high porosity and strong dirt-holding capacity. The filters are ideal for removing particles and microorganisms from a broad range of challenging pharmaceutical liquids in prefiltration process.

Key Features and Benefits

Excellent chemical capability
High retention efficiency
High flow rate and low flow differential pressure
No fiber releasing
Robust with stable performance
Stable performance and sturdy durability
Traceable
Resistance to multiple steam sterilization

Typical Applications

Intermediate products prefiltration
Blood products prefiltration
Culture media prefiltration
Prefiltration during the solution preparation process
