Standard electrochemical cell setup (redox.me)
This is a stationary solution standard electrochemical (electrolytic) cell for measurements of electrodes in a form of:
a) rod/disc (6 mm dia.),
b) thin film deposited on a flat substrate (using a sample holder) and
c) free-standing membrane (using the basic sample holder).
The working, counter, and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The cell has two spare ports for connection of e.g. thermometer, Clark electrode, pH meter electrode, or other 6 mm dia. electrode/probe.
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. The jacketed model is available here.
Application note
The reference electrode tip should be placed close to a 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.

Raman Electrochemical Flow Cell, active area: 3.5 cm2, volume: 4.5 mL (redox.me)
Read moreThis cell combines two classical analytical techniques such as electrochemistry and Raman spectroscopy, to obtain in-situ chemical information about the reactions taking place during an electrochemical experiment. It consists mainly of three elements: (i) sample holder with Tantalum (formerly Copper) foil serving as an electric contact to working electrode surface, (ii) chamber in which reference and counter electrodes are installed together with electrolyte inlet and outlet and (iii) lid which seals the cell and holds the Sapphire window. The sample consisting of a thin film of electrochemically active material deposited on a rigid or flexible substrate (working electrode) is loaded from the bottom via magnetic or screw mount. The counter or/and reference electrodes are mounted in a top casing (either 2-, or 3-electrode setup. The oval counter electrode made of e.g. Platinum wire assures uniform distribution of the field lines along the path to working electrode. During an experiment Raman laser is focused onto the surface of a thin film working electrode through a transparent Sapphire window and thin layer of electrolyte (total optical path of 3.25 mm). The electrolyte thickness of 2.25 mm ensures free diffusion of ions (e.g. protons) and its counter ions.
The electrode adapter for installing 6 mm dia. electrodes inside Raman ECFC is available here. It enables using disk electrode, plug with clip or any other rod-shape electrode (e.g. graphite rod) or current collector (e.g. metal mesh, graphite coated metal mesh, metal foil, graphite coated metal foil, metal foam, carbon woven and non-woven fabrics, carbon paper, etc.) as working electrode instead of a flat electrode in default Raman ECFC configuration.
The screw mount variant of Raman ECFC can be converted into GDE Raman ECFC by using Gas Compartment. This conversion allows installation of Gas Diffusion Electrodes as working electrode.
The cell elements are constructed with materials that are inert to the sample (PEEK, Fluorocarbons). It well fits aqueous (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 (in an external reservoir).
Application note:
This cell can be used to track kinetic phenomena such as the near-surface proton concentration changes during oxidation and reduction reaction at working electrode. It can be also used to identify materials such as carbon, metal oxides, polymers and electrolytes, and to determine their structure and distribution. Various metals are suitable for this cell as auxiliary electrode including Platinum, Gold and Silver.Specification:

Activation furnance for electrochemical sensors
Read moreThe activation furnance is a device used for curing individual sensors of the AC1 type. At a defined temperature (up to 1000 °C) depending on the electrode and sensor materials. When the sensor is cured, the surface of the electrodes is cleaned from surface oxides and organic impurities, which results in regeneration of the sensor or its activation. In this way, for example, old sensors with immobilized enzyme layers can be cured for reuse – see example at the end ot the document.
