Description

General description

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).

Application

Certipur® buffer solution (di-sodium tetraborate buffer; pH 9.22 at 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.

Packaging

1 l in Plastic bottle
