{"product_id":"cmictfppc","title":"Four-Probe PTFE Cell for Ionic Conductivity Testing of Membranes, CMICTFPPC","description":"\u003cp\u003eA Four-Probe PEEK Cell is an electrochemical testing fixture designed to measure the in-plane ionic conductivity of polymer electrolyte membranes (e.g., PEMs, AEMs, or solid-state ion exchange membranes). Constructing the cell housing out of PEEK (Polyetheretherketone) provides exceptional chemical inertness, high mechanical rigidity, and high-temperature tolerance (\u0026gt;200°C), making it ideal for testing under aggressive acidic\/alkaline vapor or hot humidified gas streams.\u003c\/p\u003e\n\u003cp\u003eThe key components of the PEEK testing cell are: (1) \u003cstrong\u003ePEEK Cell Body\u003c\/strong\u003e: Machined top and bottom blocks with gas\/liquid flow channels or open exposure windows for relative humidity (RH) control. PEEK prevents ion contamination from cell leaching. (2) \u003cstrong\u003ePlatinum (Pt) Contacts\u003c\/strong\u003e: Four parallel Pt wires or foil strips embedded at fixed intervals in the PEEK block to prevent corrosion in aggressive ionomer environments. (3) \u003cstrong\u003eSpring-Loaded Clamping\u003c\/strong\u003e: Ensures uniform, reproducible contact pressure on delicate or swelling membrane strips without tearing the sample. (4) \u003cstrong\u003eEnvironment Exposure Window\u003c\/strong\u003e: Exposes the membrane strip to controlled temperature (20°C - 120°C) and relative humidity (20% - 100%RH) inside an environmental chamber.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 284.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCMICTFPPC (C-MICT-FPPC) \u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 130.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 130.4px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 130.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eCell Body: PTFE\u003c\/li\u003e\n\u003cli\u003eFour-Probe Electrodes: Working Electrode (WE), Counter Electrode (CE), Reference Electrode (RE), and Sensing Electrode (SE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMICTFPPC_02_100x100.jpg?v=1785367443\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMetal Wire Electrode: Silver (Ag) or Platinum (Pt)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 67.2px;\"\u003e\u003cem\u003eMembrane Testing\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe membrane was placed across the four-probe metal wires and fixed\/tightened by the frame and screws. \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e         \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMICTFPPC_03_100x100.jpg?v=1785368688\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\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;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThe cell components should be thoroughly cleaned and dried after use. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"YYHEQ","offers":[{"title":"Ag Wire","offer_id":48086484877542,"sku":"CMICTFPPCAg","price":499.0,"currency_code":"USD","in_stock":true},{"title":"Pt Wire","offer_id":48086484910310,"sku":"CMICTFPPCPt","price":799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMICTFPPC_main.jpg?v=1785366558","url":"https:\/\/echemsupplies.com\/products\/cmictfppc","provider":"EChem Supplies","version":"1.0","type":"link"}
