HI7082 is a 3.5M potassium chloride solution designed to refill the electrolyte solution of double junction electrodes. Double junction electrodes contain two chambers for electrolyte. An inner chamber that has the Ag/AgCl reference wire with a fill solution KCl + AgCl fill solution and an outer chamber that has a KCl fill solution. Using the KCl in the outer chamber provides for a silver-free solution. This is important since silver can precipitate very easily in the presence of heavy metals and a biological buffer called Tris. This precipitate can clog the outer reference junction resulting in instability and long response time. Hanna’s electrolyte fill solutions are made using high-quality reagent-grade chemicals and are manufactured to the highest standards of precision and accuracy.
