General description
Certipurยฎ certified secondary standard reference materials are used to precisely calibrate and monitor pH measurement instruments and buffer solutions. They are analyzed in our ISO/IEC 17025 and ISO 17034 accredited calibration laboratories against certified primary standard reference materials (SRM) in accordance with DIN 19266, IUPAC, NIST, Ph. Eur and USP. Certipurยฎ reference materials offer maximum accuracy, reliability and convenience and help avoid costly repeat analyses.
Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

Application
Potassium dihydrogen phosphate/ di-sodium hydrogen phosphate [pH(S)=6.86โ
/pH(S)=7.41โ (25 ยฐC)] is a certified secondary standard buffer solution 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 the relevant data for the quality management system.
- The pH value of this Certipurยฎ buffer solution is qualified using differential potentiometry with two platinum hydrogen electrodes against NIST & PTB primary reference materials [pH(S)=6.86
5 /pH(S)=7.413 (25 ยฐC))]. - This buffer standard has a guaranteed shelf life of 4 years.
- It is a Certified Reference Material (CRM) offered in neat format. Solution of this standard is prepared in-house per instructions in European Pharmacopoeia (Ph. Eur. 2.2.3).
- Intended for extremely precise calibration, qualification and monitoring of pH instruments and routine assessment of their performance.
Analysis Note
pH-value (25โยฐC): 6.861 - 6.867
