产品说明

一般描述

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.

应用

di-Sodium tetraborate decahydrate [pH(S)=9.180 (25 ℃)] is a certified secondary standard reference buffer used as a calibration buffer standard for pH instruments or pH electrodes.

特点和优势

  • 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 Certipur® buffer solution is measured using differential potentiometry with two platinum hydrogen electrodes against NIST & PTB primary SRMs [pH(S)=9.180 (25 ℃)].
  • 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.
