Reference electrodes including Ag/AgCl and non-aqueous Ag/Ag+ electrodes

High quality reference electrodes suitable for cyclic voltammetry electrochemistry cells


Aqueous Ag/AgCl and non-aqueous Ag/Ag+ reference electrodes are two of the most commonly used reference electrodes for cyclic voltammetry and other electrochemical studies.

Aqueous Ag/AgCl
reference electrode

Aqueous Ag/AgCl reference electrode

Silver wire coated with silver chloride in direct contact with saturated potassium chloride, typically 3M in concentration in distilled water

Simple, stable, and capable of miniaturization

Just £83.00

Non-aqueous Ag/Ag
reference electrode

Non-aqueous Ag/Ag reference electrode

Silver wire in direct contact with 0.01N silver nitrate of acetonitrile solution sealed with a ceramic frit

Ideal when organic solvent such as acetonitrile is used in the electrolyte system

Just £83.00

Reference electrodes are used as the third electrode in three electrode electrochemical cell systems for cyclic voltammetry and similar studies. They are sometimes referred to simply as the third electrode.

Importantly, reference electrodes have a stable, known and well-defined electrochemical potential. The composition of a standard reference electrode should remain effectively unchanging and constant during the process of electrochemical test and measurement. The role of the reference electrode is to provide a stable potential for controlled regulation of the working electrode potential and in doing so allow the measurement of the potential at the working electrode without passing current through it.

An ideal reference electrode should also have zero impedance. This is determined by the resistance of its isolation junction.

Our aqueous Ag/AgCl and non-aqueous Ag/Ag reference electrodes are sold sealed in a ceramic frit junction, which separates the internal filling solution of the reference electrode from the test electrolyte. It is advised that the reference electrode should be in as close contact to the working electrode as possible to reduce Ohmic drop between them.
