OptiPes PESE Cartridge

PESE - Single Layer PES Cartridge

Brand OptiPes
Media: Liquids
Micron Ratings: 0.1 to 1.2 µm
Filter Type: Pleated Membrane

Masterfilter PESE filter cartridges feature a unique single layer, asymmetric hydrophilic polyethersulphone membrane. This membrane is characterized by excellent throughput and higher durability in many applications such as biological pre-filtration and beverage pre-filtration before the final filtration with our PESS, DPES ( PESA,PESF) final filters. Higher flow rates than any other sterilizing grade filter cartridge offers, so Masterfilter PESE filter assures thereby the most economic design of filtration systems.
