Description
Application
Used for calibrating pH electrodes and meters operating in highly alkaline conditions (pH 12-14) quality control of pH instrumentation validation of pH measurement systems in pharmaceutical manufacturing and wastewater treatment analysis requiring high pH accuracy.
Purpose
Ensures accurate traceable pH calibration in analytical labs compensating for temperature effects and providing NIST-traceable standards for reproducible results in quality control and research.
General Description
This buffer is typically a clear colorless solution composed primarily of sodium hydroxide potassium chloride (for ionic strength) and boric acid or calcium hydroxide precisely formulated to maintain pH 12.46 at 25C with 0.05 accuracy.
