2-C BM EC 50 mL - Two-compartment Bottom Mount Electrochemical Cell 50 mL
This is a stationary solution two-compartment cell for measurements of a thin film deposited on a flat substrate. The sample is loaded from the bottom via screw mount, while counter and reference electrodes are mounted in a top casing (either 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 magnetic mount version of this cell, as well as customization for other substrates sizes is available on request.
The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM/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.
The reference electrode tip should be placed close to the bottom of the chamber (3-5 mm), where the working electrode is exposed to the electrolyte. This will ensure a negligible 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. For troubleshooting instruction see the redox.me blog post.
