Used for calibration of pH meters in the high (alkaline) range. Applied in analytical laboratories and research experiments. Useful in quality control for processes involving strong bases. Employed in electrochemical and industrial testing.

Its main role is to provide a stable and accurate reference for highly alkaline conditions ensuring reliable pH measurement and control in laboratory and industrial environments.

A strongly alkaline aqueous solution with a stable pH of 13.00 at 25 deg C. It is typically prepared using strong bases (such as sodium hydroxide) and formulated to resist changes in pH when small amounts of acids or bases are added.
