Horiba pH Buffer Standard Solution pH 12.46 @ 25 °C 500 mL

Horiba pH Buffer Standard Solution pH 12.46 @ 25 °C, 500 mL (500-12)

The Horiba pH 12.46 Buffer Solution (Model 500-12) provides a ready-to-use calibration standard with a stable pH value of 12.46 ± 0.02 at 25 °C, specifically formulated for highly alkaline pH meter calibration. This buffer supports accurate calibration and verification of pH meters used in applications where measurements extend into very high pH ranges.

Horiba formulates this solution to ensure consistent, reproducible calibration performance, helping users maintain reliable pH measurements in laboratory, industrial, and research environments. Because the solution comes fully prepared, users can perform calibration immediately without dilution or additional preparation, reducing setup time and minimizing calibration errors.

The 500 mL bottle provides sufficient volume for repeated calibration cycles and suits routine use in quality control laboratories, chemical processing facilities, environmental testing, and educational institutions. This buffer works with benchtop, handheld, and portable pH meters designed for alkaline measurements.
