Reference Electrode, Mercury/Mercury Oxide, Alkaline Resistant, Single Junction

Part Number
RREF0038

The standard-sized, single junction, alkaline resistant mercury/mercury oxide (Hg/HgO) reference electrode is filled with 4.24M KOH solution. The refrerence electrode body is 9.5 mm OD, therefore ideally used with Standard volume electrochemical cells, especially the alkaline resistant RDE/RRDE cell kit. The reference electrode is designed to be pass through a 14/20 style 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. This reference electrode does not contain any glass or ceramic parts, and is therefore resistant to strong alkaline conditions. Pine Research recommends proper storage and use of reference electrodes. A variety of useful tools for storage and care are shown below.
