Ag/AgCl and non-aqueous Ag/Ag+ reference electrodes
High quality reference electrodes suitable for cyclic voltammetry electrochemistry cells
Aqueous Ag/AgCl reference electrodes and non-aqueous Ag/Ag+ reference electrodes are two of the most commonly used types for cyclic voltammetry and other electrochemical studies. Our low price aqueous Ag/AgCl and non-aqueous Ag/Ag reference electrodes make no compromises on quality and are sold sealed in a ceramic frit junction.
On top of our site-wide large order discount offer, you can now save 5% per electrode when you buy a pack of five and 10% per electrode when you buy a pack of ten. A non-aqueous Ag/Ag+ reference electrode is also included with the Ossila Potentiostat and both variants are available in our amazing value electrochemical cell kits.
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 (not included)
Simple, stable, and capable of miniaturization
Non-aqueous Ag/Ag reference electrode
Silver wire for use in direct contact with 0.01M silver nitrate of acetonitrile solution (not included) sealed with a ceramic frit
Ideal when organic solvent such as acetonitrile is used in the electrolyte system

Reference electrode placement
For a standard three electrode cell, the reference electrode should be placed in a frit within the cell. This separates the reference solution from the studied solution. Frits are porous (so that a complete circuit can be formed) but restrict the rate at which the two liquids can mix.
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.
Reference electrodes vs. pseudo or quasi reference electrodes
Pseudo reference electrodes, also known as quasi reference electrodes, are reference electrodes which do not have a surrounding reference solution. Since their potential is not defined using a known concentration of ions, pseudo reference electrodes are more likely to suffer from potential drift. This leads to less accurate results.
