EASY TO USE in the sachet for quality control (one time use)
Quality Standard for pH -Analysers
These pH quality control standards in sachets are very helpful and easy to use when being outside as a sample taker. Often the pH value has to be determined during sample taking of drinking and waste water. Therefor the pH analyser has to be tested on-site. Here the sachets for a one-time use come in handy. Of course it is a little more waste but that is the price you have to pay for conformal measurements. Further contaminations can be excluded when using these sachets. They are available for all standard pH values that are of interest. Also available as conductivity standards!

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
