{"product_id":"cnfmtfc","title":"Flow Cell for Nanofiltration (NF) Membrane Testing, CNFMTFC","description":"\u003cp\u003eA nanofiltration (NF) flow cell is a specialized laboratory apparatus used to test the performance of nanofiltration membranes on a small scale. Unlike dead-end stirred cells, flow cells operate using crossflow (tangential) filtration, which mimics industrial-scale spiral-wound elements by sweeping the feed across the membrane surface to reduce \"concentration polarization\" and fouling\u003c\/p\u003e\n\u003cp\u003eIn a flow cell, a pressurized feed solution is pumped across the surface of a flat-sheet membrane coupon. (1) \u003cstrong\u003ePermeate\u003c\/strong\u003e: The liquid that passes through the membrane. In NF, this usually contains water and monovalent ions (like Na+ or Cl-). (2) \u003cstrong\u003eRetentate (Concentrate)\u003c\/strong\u003e: The portion of the feed that does not pass through. it carries away the rejected multivalent ions (like Ca^{2+} or Mg^{2+}) and organic molecules. (3) \u003cstrong\u003eCrossflow Velocity\u003c\/strong\u003e: The speed at which the fluid travels across the membrane. Higher velocities help \"scrub\" the membrane surface, preventing the buildup of a cake layer.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 528.45px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCNFMTFC (C-NFMT-FC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 126px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 126px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 126px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003ePlate Material: All-in-One Manufacturing SS316L\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMembrane Frame: SG (0.5 mm thickness)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSealing Gasket: Silicone\u003c\/li\u003e\n\u003cli\u003eTubing Connection: O.D. 8 mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eM8 screw for tightening (8 pieces)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 54px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 54px;\"\u003e\u003cem\u003eTesting Membrane Sizes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 54px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMembrane should be \u0026gt;40mm*50mm\u003c\/li\u003e\n\u003cli\u003eEffective membrane testing area: 18mm*28mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 137.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 137.4px;\"\u003e\u003cem\u003eAssembling Diagram\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 137.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cp\u003e        \u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CNFMTFC_02_160x160.png?v=1772988844\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 136.25px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 136.25px;\"\u003e\u003cem\u003eFlow Pump (\u003cspan style=\"color: rgb(247, 8, 8);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 136.25px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe flow pump can be supplied upon request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e      \u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMEAFESFC_flow_pump_160x160.png?v=1772439579\" width=\"84\" height=\"69\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003eThe cell components should be thoroughly cleaned and dried after use. \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e1. \u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0376738805008367\"\u003eK.
