Featuring a dual-layer polyethersulfone (PES) membrane—a 0.8 µm prefilter layer permanently fused over a 0.2 µm final rated membrane—this capsule maximizes total throughput and dirt-holding capacity while protecting the final sterilizing layer from premature fouling. The naturally hydrophilic PES membrane is intrinsically low in protein binding and extractables, ensuring critical biomolecules remain intact during filtration. Encapsulated in a thermally welded, filler-free polypropylene housing, the unit is fitted with a removable filling bell on the outlet nozzle to prevent atmospheric contamination and splashing during sterile bottle-filling operations.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Attributes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAsymmetric Dual-Layer PES Membrane: Combines a 0.8 µm depth prefilter layer and a 0.2 µm sterilizing membrane to maximize fluid throughput and extend filter life in viscous or particulate-laden solutions.\u003c\/li\u003e\n\u003cli\u003eExtremely Low Protein Binding: Polyethersulfone membrane chemistry ensures minimal loss of valuable proteins, enzymes, growth factors, and active pharmaceutical ingredients.\u003c\/li\u003e\n\u003cli\u003eIntegrated Filling Bell Outlet: Includes a protective splash-guard filling bell on the downstream nozzle to ensure sterile, splash-free dispensing into open media bottles and carboys.\u003c\/li\u003e\n\u003cli\u003eThermally Welded Polypropylene Housing: Self-contained polypropylene shell eliminates glues, resins, and adhesives, minimizing chemical extractables and leachables.\u003c\/li\u003e\n\u003cli\u003eVented Capsule Design: Features an integrated high-point vent to clear trapped air and maximize active filtration membrane surface area during startup.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog \/ Part Number: 6715-7582\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: Whatman (Cytiva \/ GE Healthcare)\u003c\/li\u003e\n\u003cli\u003eEquipment Category: Encapsulated Bioprocess Capsule Filter with Filling Bell\u003c\/li\u003e\n\u003cli\u003eMembrane Material: Dual-Layer Polyethersulfone (PES)\u003c\/li\u003e\n\u003cli\u003eHousing \u0026amp; Core Material: Polypropylene (PP)\u003c\/li\u003e\n\u003cli\u003ePore Size Rating: 0.8 µm Prefilter \/ 0.2 µm Final Sterilizing Grade\u003c\/li\u003e\n\u003cli\u003eEffective Filtration Area: 750 cm squared (116 sq. in.)\u003c\/li\u003e\n\u003cli\u003eInlet Connection: 1\/4 in. to 3\/8 in.
