USB Potentiostat Galvanoplot
USB 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).

Metal Wire Auxiliary Electrode – 50HX15 0.6/250 mm (redox.me)
Read moreThe metal wire counter (auxiliary) electrode is provided in the electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.
Application note
The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package).Specification

Sample Holder 25 mm x 25 mm (redox.me)
Read moreThe sample holder (known also as flat specimen holder) is used for holding flat, circular or square/rectangular samples. It enables contacting the sample from the front (e.g. ITO/FTO glass, Monolayer Graphene on SiC, or Boron-Doped Diamond thin film on various substrates) and from the back (e.g. metal specimen, Glassy Carbon plate, Boron-Doped Diamond plate). The default nominal aperture is 1cm2, but other value can be provided on request. The large electrical contact with Tantalum (formerly Copper) foil surface (not being in contact with an electrolyte) ensures optimal current collection by minimizing electrical resistance and unifying current distribution. The rod with electrical connection has a diameter of 6 mm, which makes the sample holder compatible with our voltammetry cells and jacketed cells, as long as it fits in. We may also provide an adapter to install this sample holder in openings larger than 6 mm dia.
The sample holder elements are constructed with materials that are inert to the electrochemical system (PEEK, Fluorocarbons). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is well sealed which prevents the electrolyte to leak inside.
Application note
The sample holder is used largely for corrosion studies. It can be installed in a beaker type cell as well as in testing environments such as open water reservoirs, cans, tanks etc. It can also be used wherever it is necessary to make an electrode using a thin layer of an active material deposited on a flat substrate (conducting or insulating).Specification
