{"product_id":"polyamide-9620","title":"Polyamide, for column chromatography, 250 g, plastic","description":"\u003cp\u003ePolyamide for column chromatography is a polymeric stationary-phase material supplied for laboratory separation and purification work. This grade is intended for column chromatography and is characterised by a density of 1,14 g\/cm³, with CAS number 25038-54-4. It is Polyamide media are selected when polar interactions, including hydrogen bonding, contribute to retention during fractionation of organic mixtures, natural-product extracts or synthetic intermediates. The material from manufacturer Carl ROTH fits classical open-column and low-pressure chromatography setups used alongside other stationary phases. Laboratories can dispense the polymer as required for slurry or dry packing according to their own protocols. Within polymer and chromatography applications, this polyamide serves as a dedicated medium where polyamide-based selectivity is required.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/sorbents-silica-gel-and-ion-exchangers\"\u003eSorbents, silica gel \u0026amp; ion exchangers\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/spe-and-sample-preparation\"\u003eSPE \u0026amp; sample preparation\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAppearance: white powder\u003c\/li\u003e\n\u003cli\u003e\u0026gt;0,315 mm: ≤15 %\u003c\/li\u003e\n\u003cli\u003epH-value: 5.5-7.5\u003c\/li\u003e\n\u003cli\u003eWater: \u0026lt;5 %\u003c\/li\u003e\n\u003cli\u003eAsh content: \u0026lt;0.3 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 25038-54-4\u003c\/li\u003e\n\u003cli\u003ePack sizes: 250 g, 100 g\u003c\/li\u003e\n\u003cli\u003eDensity: 1,14 g\/cm³\u003c\/li\u003e\n\u003cli\u003eProduct type: Polyamide polymer\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-9620-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNTA0NXxhcHBsaWNhdGlvbi9wZGZ8YURSbEwyaGhNUzg1TWpVME9UVTVNRGczTmpRMkwxTlFSVnBmT1RZeU1GOUZUaTV3WkdZfDBiYmQ1MTMyMzMzYjhjMDllZGU2NGYwNGU5MWY1NjAwY2QyNmQ3MTJlZjJlMGExNzE3ZDI0ZGUwZmU5Njg5MjE\" 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-9620-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzgzNTl8YXBwbGljYXRpb24vcGRmfGFERmtMMmd5TWk4NU1qQTJPRE16TWpFM05UWTJMMU5FUWw4NU5qSXdYMFJGWDBWT0xuQmtaZ3wyZjBkMjY0M2Y2ZjUxNWFmOWVkOTI4ZTIxOTE3OTA0YmNkYjJmNWMyOTk1ODg1NTJhZmY4YTI5OWMwZmQ1YzE2\" 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 g \/ 1 piece","offer_id":56173544112460,"sku":"9620.2","price":85.9,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56173544145228,"sku":"9620.2","price":81.61,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56173544177996,"sku":"9620.2","price":77.31,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56173544210764,"sku":"9620.1","price":181.7,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56173544243532,"sku":"9620.1","price":172.62,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56173544276300,"sku":"9620.1","price":163.53,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-9620_d19df303-ddd4-433b-830a-ad3fb607142e.jpg?v=1766444030","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/polyamide-9620","provider":"Luminix Health","version":"1.0","type":"link"}
