{"product_id":"ches-9166","title":"CHES, PUFFERAN®, min. 99 %, 25 g, plastic","description":"\u003cp\u003eCHES is a zwitterionic biological buffer offered as PUFFERAN® grade with a minimum purity of 99 %. Identified by CAS number 103-47-9 and EG number 203-115-6, it has the empirical formula C₈H₁₇NO₃S and a molar mass of 207,29 g\/mol. CHES is a standard Good’s buffer component for molecular biology and biochemical applications that require stable pH control in the alkaline working range. Typical uses include enzyme assays, protein handling and other aqueous buffer systems where a well-defined sulfonic acid buffer salt is preferred. This variant is CHES from manufacturer Carl ROTH provides clear chemical identity data to support documentation, recipe design and reproducible buffer formulation in life-science and molecular biology laboratories.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/biological-buffers\"\u003eBiological buffers (Tris, HEPES, MOPS)\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/buffers-and-ph-solutions\"\u003eBuffers \u0026amp; pH solutions\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (titr.): ≥99.0 %\u003c\/li\u003e\n\u003cli\u003eLoss on drying: ≤1.0 %\u003c\/li\u003e\n\u003cli\u003e280 nm: ≤0.05\u003c\/li\u003e\n\u003cli\u003e260 nm: ≤0.04\u003c\/li\u003e\n\u003cli\u003eCAS number: 103-47-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 25 g, 100 g, 500 g\u003c\/li\u003e\n\u003cli\u003eEG nr.: 203-115-6\u003c\/li\u003e\n\u003cli\u003ePurity: min. 99 %\u003c\/li\u003e\n\u003cli\u003eMolar mass: 207,29 g\/mol\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-9166-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDU2OXxhcHBsaWNhdGlvbi9wZGZ8YURNMEwyZzROQzg1TWpVME9UVXlNemN3TWpBMkwxTlFSVnBmT1RFMk5sOUZUaTV3WkdZfDUzM2JkNDRjNjY4MDhlZTZlMGQ2MzcyYmEwY2MzMzk1NGQyMzJmMDdhNmM5NmVmZDMxY2ZlZTBiMGRlOTNmNjc\" 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-9166-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDAzMzN8YXBwbGljYXRpb24vcGRmfGFEWTJMMmhoTXk4NU1qQTJPREl6TlRFNE1qTTRMMU5FUWw4NU1UWTJYMFJGWDBWT0xuQmtaZ3wxYzExOTI2MWVjYTgyYTE0NThmNzdlOGI2MTY1NDczOGY3YWE0MzAwMDJhMjY5OThkYjYyNzQ0NzEzMWNlY2Q3\" 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":"25 g \/ 1 piece","offer_id":56173487751500,"sku":"9166.1","price":48.95,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56173487784268,"sku":"9166.1","price":46.5,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56173487817036,"sku":"9166.1","price":44.06,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56173487849804,"sku":"9166.2","price":166.65,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56173487882572,"sku":"9166.2","price":158.32,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56173487915340,"sku":"9166.2","price":149.99,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56173487948108,"sku":"9166.3","price":590.2,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56173487980876,"sku":"9166.3","price":560.69,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56173488013644,"sku":"9166.3","price":531.18,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/9166-SF-1000Wx1000H_5e8f9e63-7bda-4026-ae14-84b954284ca8.jpg?v=1766443871","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/ches-9166","provider":"Luminix Health","version":"1.0","type":"link"}
