Reference Electrode, Silver/Silver Chloride, Single Junction
Part Number
RREF0021
The standard-sized, single junction, silver/silver chloride (Ag/AgCl) reference electrode is filled with 4M KCl with AgCl solution. The refrerence electrode body is 9.5 mm OD, therefore ideally used with Standard volume electrochemical cells. The reference electrode is designed to be pass through a 14/20 ground glass joint and held in place by the included PTFE adapter, which can be adjusted to control the immersion depth of the reference electrode into the cell. Pine Research recommends proper storage and use of reference electrodes. A variety of useful tools for storage and care are shown below.

Compatibility Notice
Avoid using this reference electrode with the following: NH3 buffers, sulfides, perchlorates, non-aqueous/organic solvents, and alkaline solutions stronger than 0.1M OH–.
Thermal Stability Range: 10°C - 80°C
Electrode damage may occur at temperatures beyond recommended range. This range is provided for electrodes with PEEK shrouds.
Best Practice Suggestion: Employ a Laboratory Master Reference Electrode
A master reference electrode is a pristine, unused electrode kept exclusively to verify the accuracy of your active laboratory electrodes. By periodically measuring the potential difference between your everyday electrodes and the master in a shared electrolyte solution, you can quickly detect degradation and prevent experimental errors. To maintain its reliability as your ultimate baseline, the master electrode must never be used in actual experiments.
Compatible with Salt Bridge Kit
This reference electrode is compatible with the Salt Bridge Kit. A salt bridge enables use of a reference electrode in challenging conditions such as elevated temperature, solvent incompatibility, and chemical contamination risk.
