2-CEC+ 50 mL - Two-compartment Electrochemical Cell with additional inlet/outlet
This is a stationary solution two-compartment electrochemical cell for measurements of electrodes in a form of: a) rod/disc (6 mm dia.), b) thin film deposited on flat substrate (using a wire clip) and c) membrane (using a wire clip). The working, counter and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The counter electrode is placed in a small glass compartment separated from the other electrodes by a ceramic frit (2 mm thick Al2O3 nanoporous disk). This small compartment is equipped with a separate inlet and outlet for easy filling with an electrolyte and evacuation of gaseous products. The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte. After removal of the counter electrode glass compartment, the cell gets the functionality of a Basic Electrochemical Cell – BEC 50 mL
The reference electrode tip and working disk electrode tip should be placed at the middle of the membrane. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment. Magnetic stirring during the experiment may influence the measurement significantly.
