Electrochemical Cell for Three Electrode System
Electrochemical cells and cell kits for cyclic voltammetry
Electrochemical cells available with or without working, counter and reference electrodes
Three electrode electrochemical cells designed for cyclic voltammetry studies. Available as stand alone electrochemical cells or as electrochemical cell kits comprising of both the cell and three electrodes.
Electrochemical Cell Kits
*Please see 'specifications' for more details
The Luggin type of electrochemical cell has a gas bubble filter inlet to reduce the gas shock and bubbling to the solution and a reference electrode pocket bridge that brings the reference electrode a closer contact to the working electrode.
The electrochemical cell kit is complete with the electrochemical cell itself and three electrodes including a platinum disc working electrode, a platinum wire counter electrode and a non-aqueous Ag/Ag+reference electrode. Together with the Potentiostat for Cyclic Voltammetry developed at Ossila, it offers a unique experience of cyclic voltammetry studies either in solution or in film.

The electrochemical cell is where the chemical reaction happens by passing electricity through the electrodes. With the potentiostat and selected three electrodes, cyclic voltammetry can be carried out to obtain both oxidation and reduction potentials of the semiconducting materials, i.e. OLED small molecules or OPV polymers. Highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels can thus be calculated from the measurements.
What is an Electrochemical Cell?
An electrochemical cell is a device that is used either to generate electricity from a spontaneous chemical reaction or that uses electricity to drive a non-spontaneous chemical reaction.
The electrochemical cell with three electrodes is an electrically driven electrolytic type of cell that is designed for the use of cyclic voltammetry.
The Three Electrode System
For a better control and measurement of the current and potential going through the cell during the electricity driven chemical reaction, it is better to use a three electrode system to reduce and compensate the potential changes caused by large currents passing through the working and counter electrodes.
Apart from working electrode where chemical reactions happen and the counter electrode which serves as a current source, there is the third electrode called capillary reference electrode in the three electrode system. Not passing any current, the reference electrode is to act as a reference in measuring and controlling the working electrode potential. Ideally, the reference electrode should be placed as close as possible to the working electrode surface, i.e. the use of the Luggin capillary reference electrode to reduce the current resistance (I times R) drop since the bad conducting of organic solvents. This is also referred to as Ohmic drop which is the amount of potential lost from the reference electrode to the working electrode, caused by the Ohmic resistance between these 2 electrodes.
Electrochemistry is a powerful tool to probe reactions involving electron transfers, while cyclic voltammetry has long been well known for its versatile applications in a number of areas such as chemistry, physical chemistry, biochemistry and biology involving electron transfer process.
The electrochemical cell of 3 electrode system can potentially be used, not limited to, for the following characterization and measurements of electrically driven chemical reactions of metals, metal complexes, inorganic and organic compounds including polymers.
- Chemical analysis and synthesis
- Redox potentials
- Metabolic processes and biosensors
- Electron transfer mechanism and reversibility of a reaction
- Thermodynamic and kinetic studies
- Energy levels of semiconducting small molecules and polymers (HOMO/LUMO)
- Battery and energy studies
