{"product_id":"ferroin-indicator-solution-t131-t131","title":"Ferroin indicator solution, for sewage analysis, for COD determination, 100 ml","description":"\u003cp\u003eFerroin indicator solution is a ready-to-use reagent prepared for sewage analysis and chemical oxygen demand (COD) determination. The aqueous indicator has a density of 1,006 g\/cm³ and a boiling point of 100 °C, matching typical water-based titration media used in environmental laboratories. Supplied in a 100 ml pack, it supports measuring methods and titration workflows where a clear redox end-point is required during COD and related wastewater assessments. Ferroin indicator solution from manufacturer Carl ROTH fits routine environmental analysis benches that standardise on ferroin for endpoint detection. The stated physical properties help operators plan heating, storage handling, and transfer steps within ordinary laboratory conditions. Use this solution when establishing or maintaining COD titration series, sewage monitoring protocols, and general volumetric procedures that call for a ferroin-type indicator. The compact liquid format is convenient for repeated aliquoting in quality-control and teaching laboratories focused on water and wastewater parameters.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/indicators-and-indicator-solutions\"\u003eIndicators \u0026amp; indicator solutions\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 100 ml\u003c\/li\u003e\n\u003cli\u003eDensity: 1,006 g\/cm³\u003c\/li\u003e\n\u003cli\u003eBoiling point: 100 °C\u003c\/li\u003e\n\u003cli\u003eUse: for COD determination\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-T131-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDk0NjU1fGFwcGxpY2F0aW9uL3BkZnxhRFUwTDJoallpODVNalUxTURBNU1EVTRPRFEyTDFOUVJWcGZWREV6TVY5RlRpNXdaR1l8NmEyZTljZDQ3ZDRlNGFkM2Y3MjdjM2E0Yzg4MzNiMjdiOGE2OTRjMWRmNzA0YTU1ZDRlZDYwMTJjY2IyNTlhMw\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-T131-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNjM3OTJ8YXBwbGljYXRpb24vcGRmfGFESXpMMmd4WkM4NU1qQTJPVEF4T0RrNU1qazBMMU5FUWw5VU1UTXhYMFJGWDBWT0xuQmtaZ3w1OTBhYWVmOWU2YWZkM2QyYWMzOTM4ZmMyNjA5MGNhMWI4ODhhMDc5OTJlYTZiZmM4NWQ5MjI0YmI0ZDk1ZGMx\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"100 ml \/ 1 piece","offer_id":56186152091980,"sku":"T131.1","price":48.95,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 6+ pieces","offer_id":56186152124748,"sku":"T131.1","price":46.5,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 24+ pieces","offer_id":56186152157516,"sku":"T131.1","price":44.06,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-K034_5ca52fe0-b1b5-42ba-af51-5c6a92cf9ac2.jpg?v=1766494415","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/ferroin-indicator-solution-t131-t131","provider":"Luminix Health","version":"1.0","type":"link"}
