Ready-to-use Certipur® pH Reference Buffer Solutions in Practical Sachets

If you want precision and reliable measurements combined with ease of use, Merck offers you a range of certified, ready-to-use Certipur® buffer solutions with exact reference pH values safely packed in sealed sachets. Preparation effort is thus reduced to a minimum: Just open the sachet and start calibrating. The buffer solutions come in small and handy single-use quantities (30 ml) and are always fresh, without residues and protected from contamination. 

In order to satisfy your strictest demands in equipment calibration and monitoring, the pH value of our Certipur® buffer solutions in sachets is determined with highest precision. We analyze them 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. All our Certipur® buffer sachets 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.
