Application
Sodium hydrogen carbonate/sodium carbonate [pH(S) = 10.012 (25°C)] is a certified secondary standard reference buffer used as a calibration buffer standard for pH instruments or pH electrodes.
Features and Benefits
- The product is delivered with a comprehensive, batch-specific Certificate of Analysis showing relevant data for the quality management system.
- The pH value of this Certipur® buffer solution is measured using differential potentiometry with two platinum hydrogen electrodes against NIST & PTB primary SRM [pH(S) = 10.012 (25 °C)].
- It is a Certified Reference Material (CRM) offered in neat format.
- Intended for extremely precise calibration, qualification and monitoring of pH instruments and for testing other buffer solutions.
General description
Certipur® certified secondary standard reference buffers are used to precisely calibrate and monitor pH measurement instruments and buffer solutions. They are quality controlled and qualified in our ISO/IEC 17025 and 17034 accredited calibration laboratories against certified primary standard reference materials (SRM) in compliance with DIN 19266, IUPAC, NIST, Ph. Eur. and USP. Certipur® reference materials offer maximum accuracy, reliability and convenience and help avoid costly repeat analyses.
