Single Junction Mercury Sulfate Reference Electrode

Part Number
RREF0025

HAZARDOUS MATERIALS: Additional fees may be applied to cover the costs of shipping the single junction mercury sulfate reference electrode.  This electrode also may not be available for sale in all countries.

The standard single junction mercury sulfate (Hg/Hg2SO4) reference electrode is filled with saturated K2SO4 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.

[alert color=”blue” icon=”info-circle”]See “Description” tab below for additional precautions and information.  Pine Research recommends using alternative reference electrodes.  This electrode, while free of chloride, is difficult to use and maintain relative to Ag/AgCl.  Consider use of Ag/AgCl with a salt bridge when trying to avoid chloride contamination in the cell.[/alert]
