General description
Certipur® buffer solution [di-sodium hydrogen phosphate/potassium dihydrogen phosphate buffer; pH 6.88 (20 °C)] is intended for use as a calibration standard for pH instruments or pH electrodes or as a control sample for measuring the pH value.
The ready-to-use Certipur® buffer solutions are prepared gravimetrically in our ISO/IEC 17025 accredited calibration laboratory from high-purity salts, acids and bases diluted in high-purity water. All balances are regularly calibrated with analytical weight sets traceable to primary standard reference materials from NIST and PTB. The pH-value is measured to the highest precision using a combined glass electrode after 5-point calibration (according to DIN 19268) against reference buffer solutions (according to DIN 19266, IUPAC, NIST, Ph.Eur. and USP).
