Electrochemical Test Cells
To achieve comparable results, you need a cell design with defined geometrical parameters to control the distance between the electrodes and the size of the working and counter electrode.
Before you start your electrochemical measurements, you should think about the experimental setup. Of course, you could simply immerse your three electrodes in the measuring solution and measure the current or the potential in a corrosion test. However, this approach neglects the impact of geometrical parameters, such as the distance between the reference and the working electrode, or rather between the working and counter electrode, on the measurement result. You do not achieve comparability this way.
You can do better!
To achieve comparable results, you need a cell design with defined geometrical parameters to control the distance between the electrodes and the size of the working and counter electrode. You have to work with a comparable experimental setup – with the electrochemical test cells ElyFlow and FlexCell.
Due to long-standing experience, especially in the field of fuel cell, battery and corrosion tests, we were able to construct an electrochemical cell that eliminates all known mistakes.
Description FlexCell
FlexCell is the optimized electrochemical cell for electrochemistry with a three-electrode setup.
To achieve comparable results, you need a cell design with defined geometric parameters.
FlexCell is flexible regarding samples – but rigid where it really matters: the distance between the working and counter electrode is fixed and thus defined as well as the distance between the working electrode and reference electrode.
Since FlexCell is made of PP (propylene) or PTFE (polytetrafluorethylene), it is chemical resistant.
The plastics have no influence on the field line distribution.
Both variants can be used in a pH range of pH -6 to pH 16.
The electrolyte volume is only 30 ml.
Description ElyFlow
ElyFlow is a test cell optimized for electrolyte circuits for electrochemistry with a three-electrode set-up.
To achieve comparable results, you need a cell design with defined geometric parameters.
ElyFlow is also flexible regarding to the sample (e.g. metal sheet, foils, gas diffusion electrode) – but rigid where it really counts: the distance between the working and counter electrode is fixed and thus defined as well as the distance between the working electrode and reference electrode.
Since ElyFlow is made of PTFE (polytetrafluorethylene), it is chemical resistant.
The plastics have no influence on the field line distribution.
ElyFlow can be used in a pH range of pH 10 to pH 16 by using the inserted nickel counter electrode.
For measurements in an pH range pH -2 to pH 10 you have to use the MMO counter electrode.
The electrolyte volume of the cell itself is only 25 ml.
By using external beakers and pumping systems, measurements with significantly larger electrolyte volumes are possible.

What are Electrochemical Cells?
Electrochemical cells are systems that convert energy of chemical reactions into electrical energy. Conversely, electrical energy can also be used for electrochemical reactions. A typical half-cell which is known in the electrochemistry is the so-called Daniell cell.
The Importance of Field Lines
The potentials which are to be measured are only identical on the so-called equipotential surfaces.
Homogeneous electric field lines are required for correct measurements. Here you can learn more about parallel field lines, equipotential surfaces and IR-drop.
The Importance of Haber-Luggin Capillaries
The electrolytical contact between the working and the reference electrode is made by the Haber-Luggin capillary. Haber-Luggin capillaries are reducing the IR-Drop between reference electrode and working electrode.
