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.
