BEC 50 mL - Basic Electrochemical Cell
water-based electrolyte: 220 - 250 €
organic electrolyte: 279 - 310 €
This is a stationary solution basic 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 clip electrode) and c) membrane (using a clip electrode). The working, counter and reference electrodes are mounted in a top casing either in 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 and organic solvent 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. See the assembly demonstration here.
The reference electrode tip should be placed at the level of working electrode center. 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.
