Platinum Coated Titanium Mesh Electrode with Holder – set of 10 pcs (redox.me)

The metal counter (auxiliary) electrode is provided in electrochemical cell as a current sink to shunt excess current away from the reference electrode. Platinum Coated Titanium Mesh Electrode is a cheap alternative to pure Platinum Electrodes like Platinum Gauze Electrode or Metal Wire Auxiliary Electrode. Platinum coating makes this counter electrode inert under the reaction conditions and provides catalytic properties. The electrode is installed in the Basic Sample Holder (1 pcs included in the set), which allows full immersion of the electrode in the electrolyte (wet Tantalum contact). It well fits aqueous and organic solvent electrolyte requirements. Electrode size is customizable. 

 

Application note
The Platinum Coated Titanium Mesh Electrode is fully immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the Platinum Coated Titanium Mesh Electrode for a certain amount of time. After the process, the electrode should be washed several times with ethanol and dried under the nitrogen flow. Store the electrode in a dedicated compartment to avoid scratching. Discoloration may indicate the degradation (dissolution) of the Platinum layer and oxidation of Titanium mesh. 
This electrode is used mainly in systems where there is a high risk of its contamination by organic or inorganic deposit during the electrochemical reaction. It is also a cheap replacement for pure Platinum electrode in electrodeposition processes.

  • Sample Holder 25 mm x 25 mm (redox.me)

    The 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).

  • Hanging Platinum Drop Electrode

    The Hanging Platinum Drop Electrode (HPDE) is solid phase alanogy of HMDE.

     

    The drop of liquid Pt at 2000 °C forms a drop of Pt. The surface of HPDE has nearly ideal surface which is impossible to obtain using polishing. HPDE has also spherical symmetry which enables mathematical treatment of its response.
    The material is not toxic and it is chemically stable. The only disadvantage is HPDE cleaning, which can be, however, in some cases solved by carefull insertion of the electrode tip to the flame of an alcohol burner.
    Thus HPDE can be used as reference electrode for complicated electrochemical studies, where it is necessary to distinguish the analytical signal from the signal generated by surface inhomogenities.

     

    Hanging platinum drop electrode (HPDE) is designed for measurements with thermostated cell TC4, TC5, TC6 and TC9.
