{"product_id":"viscosity-standard-n-sub-250-sub-3345","title":"Viscosity standard N250, ROTI®Calipure, 790 cSt (20 °C), 500 ml, glass","description":"\u003cp\u003eViscosity standard N250 is a ROTI®Calipure reference liquid with a stated viscosity of 790 cSt at 20 °C for higher-range viscosity calibration and determination. Physical data include a density of 0,82 to 0,83 g\/cm³, a flash point of 219 to 257 °C and a boiling point of 217 to 419 °C, supporting safe handling assessments and instrument setup. The product is packed as 500 ml in glass, suitable for repeated use in analytical, QC and physical-testing laboratories. This N250 standard from manufacturer Carl ROTH addresses applications that require a more viscous calibration medium than lower N-series grades. Defined viscosity at 20 °C enables consistent comparison between instruments, operators and sites. Typical uses include verification of viscometers, method development for viscous fluids and routine performance checks in industrial and research settings. The glass bottle format aids controlled sampling and storage during calibration campaigns, while the documented density, flash-point and boiling-point ranges help laboratories integrate the standard into existing safety and quality systems.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/viscometers\"\u003eViscometers\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/density-and-viscosity-measurement\"\u003eDensity \u0026amp; viscosity measurement\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKinematic viscosity (20 °C): 710-870 cSt\u003c\/li\u003e\n\u003cli\u003eDynamic viscosity (20 °C): 620-760 cP\u003c\/li\u003e\n\u003cli\u003eDensity (20 °C): 0.756-0.924 g\/ml\u003c\/li\u003e\n\u003cli\u003ePack size: 500 ml glass\u003c\/li\u003e\n\u003cli\u003eDensity: 0,82 to 0,83 g\/cm³\u003c\/li\u003e\n\u003cli\u003eFlash point: 219 to 257 °C\u003c\/li\u003e\n\u003cli\u003eBoiling point: 217 to 419 °C\u003c\/li\u003e\n\u003cli\u003eGrade: ROTI®Calipure\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-3345-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjQ4MnxhcHBsaWNhdGlvbi9wZGZ8YUdWaEwyZ3pZeTg1TWpVME9ESTBORFF6T1RNMEwxTlFSVnBmTXpNME5WOUZUaTV3WkdZfDdiY2JiOTcxZWJhYjRlYTQ2YzkyZjU5ZjdjMTE0NzAwZDg5MWRiNWIzNGE0MDFlYTNhNTYzMmNjNjc2MDdiOGE\" 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-3345-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDIwNjV8YXBwbGljYXRpb24vcGRmfGFHVXpMMmd4WlM4NU1qQTJOamN3TmpnNE1qZzJMMU5FUWw4ek16UTFYMFJGWDBWT0xuQmtaZ3wyZmJjYTY1YjE5MWVmYzVhOTkyYjY0MDFjMDBjY2RlZWE5MGEyZjExZDdlY2RjN2Y0MGEzN2RhMThjY2Q4ZjNk\" 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":"500 ml \/ 1 piece","offer_id":56149213086028,"sku":"3345.1","price":220.4,"currency_code":"EUR","in_stock":true},{"title":"500 ml \/ 6+ pieces","offer_id":56149213118796,"sku":"3345.1","price":209.38,"currency_code":"EUR","in_stock":true},{"title":"500 ml \/ 24+ pieces","offer_id":56149213151564,"sku":"3345.1","price":198.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-3345-3385_292157d8-7f28-46be-bcfa-f0719e940c00.jpg?v=1766434363","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/viscosity-standard-n-sub-250-sub-3345","provider":"Luminix Health","version":"1.0","type":"link"}
