The fine platinum wire suits both vertical and horizontal electrophoresis units where a durable, chemically resistant electrode is required for buffer contact and current delivery. Supplied as 1 pc and weighing 0,047 kg, the electrode is a compact spare part for laboratory maintenance and instrument servicing. Platinum is selected for electrode duty because of its conductivity and stability under typical electrophoresis running conditions. This spare electrode supports continued operation of gel systems used in life-science separation work when the original electrode is worn or damaged. It is offered within the ROTH SELECTION range for electrophoresis accessories and is specified by diameter and length so users can match existing electrode geometry. Installation should follow the guidance of the host electrophoresis unit manufacturer. With clearly defined dimensions of Ø 0,2 mm and 500 mm length, the part is straightforward to identify for inventory and replacement planning in analytical and teaching laboratories that run vertical or horizontal gels regularly.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/ph-electrodes-and-sensors\"\u003epH electrodes \u0026amp; sensors\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/ph-and-electrochemistry\"\u003epH \u0026amp; electrochemistry\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eProduct type: Platinum spare electrode\u003c\/li\u003e\n\u003cli\u003eDiameter: 0,2 mm\u003c\/li\u003e\n\u003cli\u003eLength: 500 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: Platinum\u003c\/li\u003e\n\u003cli\u003eCompatibility: Vertical and horizontal electrophoresis units\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 pc \/ 1 piece","offer_id":56117098316108,"sku":"1428.1","price":177.4,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56117098348876,"sku":"1428.1","price":168.53,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56117098381644,"sku":"1428.1","price":159.66,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/T794-1000Wx1000H_9b641863-29d7-4047-a9a3-6695bcb55e40.jpg?v=1766400113"},{"product_id":"electrolyte-lithium-chloride-1t2l-1t2l","title":"Electrolyte Lithium chloride, ROTI®Calipure 1 mol\/l in ethanol, 100 ml","description":"\u003cp\u003eElectrolyte lithium chloride is a ROTI®Calipure solution at 1 mol\/l in ethanol, prepared for use in potentiometric titration according to ASTM D664.
