This electrochemical cell is a stationary two-compartment solution with a total volume capacity of up to 50 mL, designed for electrode measurements in various forms: a) rod/disc (6 mm body diameter), b) thin films deposited on flat substrates (secured with a wire clip), and c) free-standing samples (also secured with a wire clip). The working, counter, and reference electrodes are housed in a lid, configured either in a 2-electrode or 3-electrode setup. The counter electrode resides in a separate PTFE compartment, isolated from other electrodes by a membrane (either ion-exchange or nanoporous), which can be easily replaced by removing a membrane holder fixed against the PTFE compartment. This counter electrode compartment features dedicated inlet and outlet ports for convenient electrolyte filling and gas evacuation. It is also possible to separate the reference electrode using a membrane if it requires protection from the electrolyte in the cell (for example, high pH may dissolve the ceramic frit or glass housing) or if there is a risk of contaminating the surroundings of the electrochemical reaction with electrolyte from the reference electrode (for example, chloride ions). A liquid junction adapter is used for this purpose.
Constructed from inert materials like PTFE, PVDF and other fluoro-polymers, the cell is compatible with both aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolytes. It ensures a gas-tight seal and is suitable for applications requiring the removal and exclusion of contaminants such as oxygen and water, achieved by bubbling inert gas through the electrolyte. By removing the counter electrode compartment, the cell transforms into a PTFE BEC 50 mL - PTFE Basic Electrochemical Cell, reducing its functionality accordingly.
The wire clips, counter electrode, reference electrode, RE liquid junction adapter and membranes presented in the cell pictures are not part of the set and should be ordered separately.
PTFE 2-CEC+ 50 mL - PTFE Two-compartment Electrochemical Cell with additional inlet/outlet
Application note
The materials used to construct this cell have been specifically selected for compatibility with concentrated alkaline electrolytes (including heated ones), hydrofluoric acid, or other electrolytes with which glass and PEEK are not compatible (see more here). The tips of the reference electrode and working disk electrode should be positioned at the level of the membrane to ensure minimal potential drop across the electrolyte solution during low-current experiments. This cell is compatible with various auxiliary electrodes, including metal wire, metal foil, and graphite rod electrodes. Gas bubbling through the solution should be stopped before the experiment begins. Additionally, magnetic stirring during the experiment may significantly affect the measurements.
