This professional-grade filter features a unique \"PF\" (Pre-Filter) architecture, combining a 0.8 µm pre-filter layer with a 0.2 µm final Supor® (polyethersulfone) membrane. This dual-layer construction significantly increases total throughput and prevents premature clogging, making it the industry standard for filtering cell culture media, serum-rich solutions, and complex buffers. Manufactured with a color-coded (blue\/green) modified acrylic housing, each filter is individually blister-packed and gamma-sterilized to ensure absolute purity and compliance with stringent laboratory protocols.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDual-Layer Supor® Technology:\u003c\/b\u003e The 0.8\/0.2 µm graduated pore structure provides built-in pre-filtration, allowing for faster flow rates and up to double the throughput of standard filters when handling \"dirty\" samples.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLow Protein Binding:\u003c\/b\u003e The inherently hydrophilic Supor® (PES) membrane is optimized for minimal non-specific binding, ensuring maximum recovery of high-value proteins, enzymes, and active pharmaceutical ingredients.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eGamma-Sterilized Purity:\u003c\/b\u003e Individually sealed in medical-grade blister packs and sterilized via gamma irradiation to eliminate potential EtO (Ethylene Oxide) residuals, making them safe for sensitive cell culture and clinical research.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eRobust Housing Design:\u003c\/b\u003e The 25 mm modified acrylic housing is designed to withstand operating pressures up to 75 psi (5.2 bar), featuring a female Luer-lock inlet and a male slip Luer outlet for secure connectivity.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 4187\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDiameter:\u003c\/b\u003e 25 mm\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMembrane Type:\u003c\/b\u003e Supor® (Hydrophilic Polyethersulfone \/ PES)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePore Size:\u003c\/b\u003e 0.8\/0.2 µm (Integrated Pre-filter + Final Sterilizing Layer)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eEffective Filtration Area:\u003c\/b\u003e 2.8 cm²\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHold-up Volume:\u003c\/b\u003e \u0026lt; 300 µL (with air purge)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Sterile (Gamma Irradiated); Non-pyrogenic.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePackaging:\u003c\/b\u003e Individually Sealed Blister Packs (50 per box).\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMedia \u0026amp; Serum Filtration:\u003c\/b\u003e The primary choice for sterilizing FBS (Fetal Bovine Serum) and other serum-supplemented media where high particulate loads typically cause filter failure.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eProtein Purification:\u003c\/b\u003e Ideal for clarifying protein-rich fractions and biological intermediates after chromatography or extraction steps.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eViscous Solution Processing:\u003c\/b\u003e Optimized for filtering viscous buffers or viscous biological reagents that require high-pressure manual filtration.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSample Preparation:\u003c\/b\u003e Provides an efficient, single-step method for both clarification and sterilization of small volumes (up to 100 mL) in a single device.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Pall","offers":[{"title":"Default Title","offer_id":44498197676284,"sku":"4401","price":80.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/pall-syringe-filter-02-um-supor-membrane-pes-25-mm-diameter-box-of-50-filters-filters-pall-189718.jpg?v=1733153438","url":"https:\/\/lifesciencestrading.com\/products\/pall-syringe-filter-0-2-um-supor-membrane-pes-25-mm-diameter","provider":"Life Sciences Trading","version":"1.0","type":"link"}
