Ready-to-use Certipur® pH
Reference Buffer Solutions


For the routine calibration and monitoring of your pH instruments, Merck offers a wide choice of ready-to-use buffer solutions with exact pH reference values from 1.00 to 11.00 (at 20 °C).

pH values are determined with highest precision. We analyze our Certipur® buffer solutions in our own ISO/IEC 17025 accredited calibration laboratory with a combined glass electrode and 5-point calibration according to DIN 19628 against certified primary standard reference materials according to DIN 19266. Certipur® pH reference buffer solutions are traceable to primary standard reference materials from NIST (U.S.) and PTB in Brunswick (Germany). Uncertainty data and traceability are documented in a comprehensive, batch-specific Certificate of Analysis.
