This is a stationary solution voltammetry cell designed to measure changes in specific resistivity of thin film material induced by the injection/extraction of ions from/to an electrolyte. The process is controlled through the application of voltage to the counter electrode immersed in liquid or gel electrolyte. The sample is loaded from the bottom via magnetic or screw mount, while 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/FKM 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 specific resistivity of arbitrary shape sample can be measured if the following conditions are met: the contacts are at the circumference of the sample, the contacts are sufficiently small, the sample is uniformly thick, and the surface of the sample do not contain any isolated holes. 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 blog post
