PP Disc Prefilters

Product Introduction
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.
