Platinum Coated Titanium Mesh Electrode With Holder - Set of 10 Pcs

  • $ 64944


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.
