Rated at 25 °C and tinted blue for immediate recognition at the bench, it is intended for routine multi-point calibration of pH electrodes and meters. A DAkkS certificate accompanies the solution, supporting traceable documentation in quality systems and accredited laboratories. Typical physical data include a density of about 1 g\/cm³ and a boiling point of 100 °C. The 500 ml unit quantity is convenient for repeated calibrations in analytical, process-control, and teaching settings. This DuraCal buffer from manufacturer HAMILTON is well suited to alkaline-range checks during determination of physical properties and dedicated pH-value work. Clear colour coding reduces mix-ups between standards, while the certified composition helps laboratories maintain stable reference performance across measurement campaigns in research, industrial QC, and environmental analysis.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack sizes: 250 ml, 1500 ml, 10 l\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 41116107\u003c\/li\u003e\n\u003cli\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-25C0-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzkyMnxhcHBsaWNhdGlvbi9wZGZ8YURRNEwyZzFZeTg1TWprek1Ea3hNVEV3T1RReUwxTlFSVnBmTWpWRE1GOUZUaTV3WkdZfDAxNjVkZjU2ZmVjMDRjMThhNDJiM2I4OGQyOWRiNGE4NzNlNmRmZmIwMDc1NTNiZDM4YWY5ZjI1Nzg2ODQyMDQ\" target=\"_blank\" rel=\"noopener noreferrer\" 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-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SDB-25C0-GB-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNTg2MjB8YXBwbGljYXRpb24vcGRmfGFHUTFMMmd5T0M4NU1UUXlNVEUwTnpFek5qTXdMMU5FUWw4eU5VTXdYMGRDWDBWT0xuQmtaZ3xiZjlkZmFkMjVjMWRlNmUyMjIzN2M2MGFkNDY4MDkzNTA0N2QxMzMyMjQ2ZDY2OTE0NTEyZGRlNTY5MDE4YWU2\" target=\"_blank\" rel=\"noopener noreferrer\" 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-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luminix Health","offers":[{"title":"250 ml","offer_id":58656438878540,"sku":"25C0.2","price":28.95,"currency_code":"EUR","in_stock":true},{"title":"1500 ml","offer_id":58656438911308,"sku":"25C0.3","price":95.7,"currency_code":"EUR","in_stock":true},{"title":"10 l","offer_id":58656438944076,"sku":"25C0.4","price":342.95,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/www.luminixhealth.com\/fr-be\/products\/buffer-solution-duracal-ph-9-21-25-c-25c0","provider":"Luminix Health","version":"1.0","type":"link"}
