Description
Buffer solution DuraCal pH 9.21 (25 °C) provides a defined alkaline calibration point for precise pH measurement and instrument verification. Rated at 25 °C and tinted blue for immediate recognition at the bench, it is intended for routine multi-point calibration of pH electrodes and meters. A DAkkS certificate accompanies the solution, supporting traceable documentation in quality systems and accredited laboratories. Typical physical data include a density of about 1 g/cm³ and a boiling point of 100 °C. The 500 ml unit quantity is convenient for repeated calibrations in analytical, process-control, and teaching settings. This DuraCal buffer from manufacturer HAMILTON is well suited to alkaline-range checks during determination of physical properties and dedicated pH-value work. Clear colour coding reduces mix-ups between standards, while the certified composition helps laboratories maintain stable reference performance across measurement campaigns in research, industrial QC, and environmental analysis.
