HI8071 Electrolyte Fill Solution, 3.5M KCl AgCl in FDA Bottle (30 mL x 4)

As one of the most common models of electrodes, the single junction reference electrode is made with a Ag/AgCl wire. The wire is equilibrated in a solution of KCl that is in contact with the sample to be measured, often through a porous junction. As AgCl is soluble in concentrated KCl, the electrolyte must be saturated with AgCl to prevent the plating from dissolving off of the wire. The HI8071 electrolyte solution ensures optimum measurement performance from your pH electrode.
