Redox Standard DuraCal ORP is a laboratory redox (ORP) standard specified at 271 mV. The solution is supplied in a 500 ml dosage bottle for calibration and verification of redox electrodes and ORP meters. Physical properties include a density of ~1 g/cm³ and a boiling point of 100 °C. ORP standards of defined millivolt value are used to check electrode response and to document instrument setup before measurements on process or laboratory samples. The 271 mV specification provides a working reference for routine redox measurement. This DuraCal preparation from manufacturer Hamilton is intended for electroanalytical work that requires an ORP standard of stated potential. Follow the instrument procedure for electrode calibration or verification and handle the liquid according to usual laboratory practice for calibration standards. The 500 ml dosage bottle supports repeated use with bench and portable ORP meters. Density of ~1 g/cm³ and boiling point of 100 °C describe the physical character of the liquid during routine laboratory handling. Use the standard as part of a documented calibration sequence for redox electrodes in chemical, environmental or quality-control laboratories.
