The system features a 500 mL upper filter funnel and a matching 500 mL receiver storage bottle, both molded from optically clear polystyrene. It is equipped with a high-performance, asymmetric Polyethersulfone (PES) membrane featuring a 0.45 µm pore size. Utilizing the proprietary Rapid-Flow multi-column support matrix, the unit optimizes fluid dynamics to deliver exceptionally fast flow rates and high throughput while maintaining an airtight, leak-proof seal during vacuum applications.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eAsymmetric PES Membrane: The 0.45 µm polyethersulfone membrane provides low non-specific protein binding and low extractables, ensuring the chemical composition of sensitive biological solutions remains unaltered.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eRapid-Flow Support Grid: The engineered multi-column support matrix beneath the membrane prevents target deformation and maximizes active surface area, significantly reducing filtration times compared to traditional concentric ring designs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eLeak-Proof Closure System: The receiver bottle is supplied with a heavy-duty, blue high-density polyethylene (HDPE) screw cap featuring no liner to eliminate a common source of trace contamination or chemical leaching.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eStable Base Profile: The wide, stable footprint of the receiver bottle resists tipping on the benchtop during vacuum hose attachment, enhancing laboratory safety.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eCatalog Number: 166-0045 (also written as 1660045)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eProduct Line: Nalgene Rapid-Flow\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eCapacity: 500 mL Upper Funnel \/ 500 mL Receiver Bottle\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eMembrane Material: Polyethersulfone (PES)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003ePore Size: 0.45 µm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eHousing Material: Polystyrene (PS)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eSterility: Sterile, Non-Pyrogenic, and Cytotoxic-Safe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eNeck Diameter: 50 mm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eBuffer Clarification: The industry-standard choice for filtering large volumes of laboratory buffers, reagents, and aqueous microbiological media ingredients.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eParticle Removal: The 0.45 µm pore classification effectively captures fine precipitates, cellular fragments, and dense particulates that could otherwise clog sensitive analytical instrumentation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eWorkflow Efficiency: Eliminates the tedious setup, manual cleaning, and sterilization required for reusable glass filtration hardware, allowing for immediate \"plug-and-play\" operation via standard vacuum lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003eSafe Sample Storage: The clear polystyrene receiver storage bottle serves as a robust container for short-to-medium-term cold storage of processed liquids.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eExpiration Date 02\/15\/2027\u003c\/p\u003e\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":"Thermo Scientific","offers":[{"title":"Default Title","offer_id":44624437936380,"sku":"6090","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/thermo-scientific-rapid-flow-filter-unit-045-um-pes-500-ml-case-of-12-filters-filters-thermo-scientific-331025.jpg?v=1785209859","url":"https:\/\/lifesciencestrading.com\/products\/thermo-scientific-166-0045-rapid-flow-filter-unit-0-45-um-pes-500-ml","provider":"Life Sciences Trading","version":"1.0","type":"link"}
