The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.\u003c\/p\u003e\n\u003cp\u003eIn this electrode concept, the plug is made of PTFE.

The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package). \u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003cbr\u003ehelix inner diameter: 4.8 mm\u003cbr\u003ehelix outer diameter: 6 mm\u003cbr\u003enumber of turns: 12\u003cbr\u003ewire diameter: 0.6 mm\u003cbr\u003etotal wire length: 235 mm (215 mm long helix, 20 mm long straight wire)\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntrastat data\u003c\/strong\u003e\u003cbr\u003eHS Code: 71101910 (platinum), 71081310 (gold),\u003cbr\u003eCountry of Origin: Sweden\u003cbr\u003eNET weight: 100 g\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct includes\u003c\/strong\u003e\u003cbr\u003e1x metal wire electrode with PEEK plug and selected electrical connector\u003cbr\u003e1x O-Ring\u003cbr\u003e1x glass vial\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelated products\u003c\/strong\u003e\u003cbr\u003eElectrochemical cells\u003cbr\u003ePhoto-electrochemical cells\u003c\/p\u003e","brand":"redox.me","offers":[{"title":"water-based electrolyte \/ Platinum (99.9%) \/ 1 mm dia. gold plated pin","offer_id":56885653897542,"sku":"E-A-PTFE_35HX15_Pt-1mm","price":486.0,"currency_code":"EUR","in_stock":true},{"title":"water-based electrolyte \/ Platinum (99.9%) \/ 4 mm female banana socket","offer_id":56885653930310,"sku":"E-A-PTFE_35HX15_Pt-4mm_B","price":498.0,"currency_code":"EUR","in_stock":true},{"title":"water-based electrolyte \/ Gold \/ 1 mm dia. gold plated pin","offer_id":56885653963078,"sku":"E-A-PTFE_35HX15_Au-1mm","price":486.0,"currency_code":"EUR","in_stock":true},{"title":"water-based electrolyte \/ Gold \/ 4 mm female banana socket","offer_id":56885653995846,"sku":"E-A-PTFE_35HX15_Au-4mm_B","price":498.0,"currency_code":"EUR","in_stock":true},{"title":"organic electrolyte \/ Platinum (99.9%) \/ 1 mm dia. gold plated pin","offer_id":56885654028614,"sku":"E-O-PTFE_35HX15_Pt-1mm","price":528.0,"currency_code":"EUR","in_stock":true},{"title":"organic electrolyte \/ Platinum (99.9%) \/ 4 mm female banana socket","offer_id":56885654061382,"sku":"E-O-PTFE_35HX15_Pt-4mm_B","price":540.0,"currency_code":"EUR","in_stock":true},{"title":"organic electrolyte \/ Gold \/ 1 mm dia. gold plated pin","offer_id":56885654094150,"sku":"E-O-PTFE_35HX15_Au-1mm","price":528.0,"currency_code":"EUR","in_stock":true},{"title":"organic electrolyte \/ Gold \/ 4 mm female banana socket","offer_id":56885654126918,"sku":"E-O-PTFE_35HX15_Au-4mm_B","price":540.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/5600\/3482\/files\/1_82f8602c-3359-4e0e-9dfb-1719814c6f04.png?v=1782911810","url":"https:\/\/www.thasar.com\/it\/products\/metal-wire-auxiliary-electrode-ptfe-35hx15-0-6-235-mm","provider":"Thasar S.r.l.","version":"1.0","type":"link"}
