Raman Electrochemical Flow Cell, active area: 3.5 cm2, volume: 4.5 mL (redox.me)
This 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.

USB Potentiostat Galvanoplot
Read moreUSB Potentiostat Galvanoplot is a super small, low-cost and affordable device suitable for dedicated volume applications, which is optimized for screen-printed sensor and biosensor applications. It can be used in many other research areas and with other electrochemical sensors, for corrosion measurement, battery and super-capacitors or fuel cells.
It is capable of performing all common Amperometric and Voltammetric electrochemistry protocols (CA, LSV, CV, DPV, NPV, SVW, GAL) and can be used with three electrode (WE/RE/CE) and two electrode (WE/RE-CE) setups. Plug the device directly into an Android mobile device through OTG port for a true on-site analysis experience. It is possible to choose from two types of interfaces allowing direct insertion of the BVT SPE sensors or the use of 3 classical electrodes with 2 mm banana plugs (WE, RE, CE).

SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)
Read moreThe SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.
The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H2O2 which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.* For this product, we recommend our customers use the Training Service from BVT.

Front contact photo-electrochemical H-Cell setup (redox.me)
Read moreThis is a horizontally mounted, double compartment photo-electrochemical H-Cell used to simultaneously or individually investigate thin film photo-anode and photo-cathode. The cell elements are made of PEEK and Fluoropolymers. It well fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight having two separate chambers, each equipped with gas inlet and outlet. This allows bubbling the solution and evacuating gases. Chambers are separated with an ion-exchange membrane (e.g., DuPont’s Nafion® membrane), so the electrochemical products appearing at photo-anode and (photo-)cathode do not affect the opposite electrode.
Application note:
This cell allows several approaches to perform measurements in 2- or 3-electrode setups. It is designed to investigate performance of a thin film photo-anode or photo-cathode (e.g. nanocrystalline material or conducting polymer) deposited on a rigid or flexible transparent substrate (typically fused quartz glass). The counter electrode is mounted in the second chamber either in a top casing or attached on the side of the cell as a thin film deposited on rigid or flexible substrate. The reference electrode is mounted in a top casing of the same chamber as the studied photo-electrode. Various auxiliary electrodes are suitable for this cell including metal wire, gauze and foil electrodes as well as non-metal electrodes and thin films. Typical applications include: basic photochemistry (photo-catalysis), photolytic water splitting, photoinduced charge separation and photo-corrosion.Specification:
