The standard single junction silver/silver chloride (Ag/AgCl) reference electrode is filled with 4M KCl with AgCl solution. The reference electrode fits through the standard 14/20 ground glass joints found on our standard electrochemical cells. A PTFE sleeve (included) facilitates mounting the reference electrode in the joint.
Includes 14/20 PTFE adapter, storage bottle, bottle of filling solution
Silver Chloride Reference Electrode (with sleeve to fit a 14/20 joint)
The junction at the lower end of the reference electrode is a ceramic frit that should be kept wet at all times.
If frit dries out, soak overnight in distilled water. More information about care, storage, and usage can be found in the product information sheet, which you can download from the Documentation tab.
A small vial containing 4M KCl electrode filling solution is included with the single junction Ag/AgCl reference electrode.
