VWR® Redox (ORP) Standards are high-quality reference solutions designed to verify and calibrate oxidation-reduction potential (ORP) electrodes and instruments. Manufactured using reagent-grade materials under tightly controlled conditions, these standards provide consistent and reliable performance across a wide range of values.
All standard values are measured at 25 °C and are referenced against a platinum electrode versus Ag/AgCl (3 M KCl) reference system. Each bottle includes a temperature correction table printed on the label and in the Certificate of Analysis to allow for accurate calibration at varying conditions. The solutions offer excellent stability throughout shelf life and are ideal for laboratory, field, and industrial ORP verification.
