Reference electrode DCRREF

Product Name: Double Junction Silver Chloride (Ag/AgCl) Reference Electrode

Model: DCRREF

Brand: Wuhan DC New Energies Co.，Ltd

Origin: China

The standard double junction silver/silver chloride (Ag/AgCl) reference electrode contains two filling solutions: the inner filling solution is  KCl with AgCl, while the outer filling solution is composed of 10% KNO3.  Only the outer fill solution comes in contact with electrolyte via the ceramic frit at the bottom, allowing Ag/AgCl to be used while avoiding chloride contamination.  

The outer fill solution may also be drained manually and refilled with a different aqueous solution of the user’s choice.

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.

The junction at the lower end of the reference electrode is a ceramic frit that should be kept wet at all times.  If frit dries out, soak overnight in distilled water.  More information about care, storage, and usage can be found in the product information sheet, which you can download from the Documentation tab.

A small vial containing the outer 10% KNO3 filling solution is included with the double junction Ag/AgCl reference
