Electrodes
Electrodes made of Platinum and platinum alloys distinguish themselves as electrode materials because of their high electrical conductivity and resistance to chemical attack. Due to our experience in the field of manufacturing electrodes, we are able to supply high quality solutions to meet your demands. Electrodes are made of pure Platinum or Platinum/Iridium 90/10. This material will ensure mechanical stability to make your application of the electrodes as convenient as possible. You can choose between four different designs of electrodes: Fischer, Winkler, Wölbing and Schöniger. Please find an overview of these electrodes at the bottom of this page. If required, Heraeus Materials Technology is pleased to check your request of specifically designed electrodes. Thus, only the most common electrodes are listed below.
Fischer Electrodes are sand blasted in order to increase the wire surface. This property makes these electrodes suitable for fast tests with high current densities in both, stirred and still electrolytes. As Fischer electrodes, we can supply each electrode sand-blasted, depending on your individual need.
Winkler Electrodes consist of a slit gauze cylinder. Concentrically, there is a wire spiral positioned. These electrodes may be used for electro gravimetrically identification of copper and zinc.
Wölbing Electrodes contain a gauze which is fixed stably to the central rod at the top and bottom via a solid cross. Similarly to all other designs, we supply different standard dimensions of Wölbing electrodes.
Schöniger Electrodes are made of a pure platinum wire mesh bent into a U-shape. This kind of electrodes is primarily used for the rapid determination of halogens and sulphur.
If no standard electrode fulfills your needs, we are pleased to develop together with you an appropriate design of your electrodes. Please get in contact with us and we will check possibilities to develop electrodes of your choice.
