HI-8093 Electrolyte Solution, 1M KCl + AgCl 4 x 30 mL FDA bottles

HI-8093 is a pH and ORP electrode fill solution that is supplied in a FDA compliant bottles. Each bottle contains 3.5M KCl + AgCl, which is specifically made for single junction electrodes. The electrolyte level in refillable electrodes should be checked before performing any measurements. If the level is low, refill with the proper electrolyte solution to ensure optimum performance. This simple maintenance helps guarantee adequate head pressure to promote the flow of reference electrolyte into the sample being measured.

• Fill solution for single junction pH & ORP electrodes
• Convenient 30 mL bottles
• Clearly marked bottle with expiry date and lot number

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 HI-8093 electrolyte solution ensures optimum measurement performance from your pH electrode.
