Neomeris pH Buffer Solution pH 10.01 – Alkaline Calibration Solution Reliable reference solution for pH calibration The Neomeris pH buffer solution pH 10.01 is a ready-to-use calibration solution for pH electrodes in the alkaline measurement range. With a reference value of pH 10.01 ± 0.02 at 25 °C, it enables reliable calibration of pH meters wherever high pH values require precise measurement accuracy. Safe usage and versatile applications The clear yellow color coding ensures easy identification of the pH value and prevents mix-ups during daily work. The hygienic cap protects the solution from contamination and allows clean and efficient handling. Why are alkaline reference solutions necessary for precise pH calibration? Alkaline calibration solutions are required to reliably set pH meters and electrodes in the high pH range. Calibration in only the acidic or neutral range is not sufficient when measurements are performed at alkaline pH values. The pH value does not change linearly across the measurement range. Particularly in the alkaline range, pH electrodes are more sensitive to deviations, aging, or contamination. An alkaline calibration solution (e.g., pH 10.01) ensures that the meter measures accurately exactly where it will be used. Where can the buffer solution be used? The pH buffer solution is versatile and suitable for: Laboratory analysis Environmental and water analysis Food monitoring Research & education Industrial processes
