Bottom Magnetic Mount Corrosion Cell - BMM CC 15 mL, 1cm2

This is a stationary solution corrosion cell for EIS and conventional electrochemical measurements on: (a) thin metal film deposited on flat substrate, (b) metal plate, (c) metal mesh, (d) metal wire and (e) metal ribbon. The sample is installed from the bottom via magnetic mount in between two chambers filled with electrolyte. In cases (a) and (b) bottom chamber is unused and stays dry. The counter or/and reference electrodes are mounted in a top casing (either 2-, or 3-electrode setup). 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.

Application note
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 noble metal wire and graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.
