{"product_id":"heppso-27a7-27a7","title":"HEPPSO, PUFFERAN®, min. 99 %, 25 g, plastic","description":"\u003cp\u003eHEPPSO is a high-purity biological buffer in the PUFFERAN® grade with a minimum purity of 99 %. It is defined by CAS number 68399-78-0, the empirical formula C₉H₂₀N₂O₅S and a molar mass of 289,33 g\/mol. This zwitterionic Good’s-type reagent is used in molecular biology and biochemistry whenever stable pH control is required during sample preparation, electrophoresis, nucleic-acid work or enzymatic assays. The material is HEPPSO from manufacturer Carl ROTH is chosen by laboratories that prefer buffers with limited metal-ion interaction and reproducible performance in sensitive life-science workflows. Typical applications include preparation of working buffer solutions for protein studies, cell-based assays and molecular biological protocols that depend on consistent ionic conditions. The PUFFERAN® quality level supports analytical and preparative tasks where batch-to-batch reliability matters. Researchers value the practical pack size for everyday laboratory use without unnecessary excess inventory, making this reagent a practical component of molecular biological buffer systems.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (titr.): ≥99.0 %\u003c\/li\u003e\n\u003cli\u003eAppearance: white powder\u003c\/li\u003e\n\u003cli\u003epH (1 % solution): 5.0-7.0\u003c\/li\u003e\n\u003cli\u003eLoss on drying: ≤7.0 %\u003c\/li\u003e\n\u003cli\u003eHeavy metals (as Pb): ≤5.0 ppm\u003c\/li\u003e\n\u003cli\u003eCAS number: 68399-78-0\u003c\/li\u003e\n\u003cli\u003ePack sizes: 25 g, 100 g, 500 g\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₉H₂₀N₂O₅S\u003c\/li\u003e\n\u003cli\u003eMolar mass: 289,33 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +15 to +25 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-27A7-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDQwOXxhcHBsaWNhdGlvbi9wZGZ8YURGaEwyaG1NQzg1TWpVME5qRTFOVGd3TnpBeUwxTlFSVnBmTWpkQk4xOUZUaTV3WkdZfDJiMzQwYWIwYTYwYzU4M2MzOTQxMDU4NTgwN2FiZTRiZDNjODhlZjRjYjI0ZjY1NDE3MmIwNWM5NmU5NDU4ZWI\" 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-27A7-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDY5ODB8YXBwbGljYXRpb24vcGRmfGFHWTVMMmcxWkM4NU1qQTJORFEyT0RVd01EYzRMMU5FUWw4eU4wRTNYMFJGWDBWT0xuQmtaZ3xkN2U4NTk4MWRlM2M0NTFkZjYxMDFhYjk0OTJmYzcwNmNlZjAwNWYzNzZlNjM5MmVhZDI3MzYwYjQ0YmZiMTM3\" 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":56130043609420,"sku":"27A7.1","price":68.7,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56130043642188,"sku":"27A7.1","price":65.27,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56130043674956,"sku":"27A7.1","price":61.83,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56130043707724,"sku":"27A7.2","price":252.65,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56130043740492,"sku":"27A7.2","price":240.02,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56130043773260,"sku":"27A7.2","price":227.39,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56130043806028,"sku":"27A7.3","price":987.95,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56130043838796,"sku":"27A7.3","price":938.55,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56130043871564,"sku":"27A7.3","price":889.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-27A7-SF_47ab00eb-d045-4e07-a95b-72716d6a4ccf.jpg?v=1766414806","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/heppso-27a7-27a7","provider":"Luminix Health","version":"1.0","type":"link"}
