Reference Electrode, Mercury/Mercury Sulfate, Single Junction
Pine Research suggests purchasing and using standard single junction Ag/AgCl reference electrode instead.
The standard-sized, single junction, mercury/mercury sulfate (Hg2SO4) reference electrode is filled with saturated K2SO4 solution. The internal reference electrode solution, which cannot be accessed or changed, and the external filling solution are the same. The outer filling solution can be refreshed as usual. The additional junction aids to prevent any mercury from reaching bulk 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.
