Metrohm, 6.230.8050, Electrolyte 3 mol/L KCl (50 mL)

Metrohm 3 mol/L potassium chloride electrolyte provides an aqueous reference solution for compatible electrodes incorporating an Ag/AgCl reference system. This 50 mL bottle supports maintenance of the electrolyte-filled reference compartment, helping preserve reliable ionic contact between the electrode reference element and a sample during pH measurement or potentiometric titration. Stable reference conditions reduce the risk of drifting potential and unstable endpoints caused by electrolyte depletion or inappropriate filling solutions. Laboratories use this reagent when servicing compatible Metrohm pH and electrochemical electrodes in quality control, analytical chemistry and titration workflows. The concentration is 3 mol/L KCl, rather than the nonaqueous lithium chloride or tetraethylammonium bromide electrolytes used by certain specialist electrodes. Matching the solution to the installed reference system is important for electrode performance.
