Platinum electrodes

IAM Drijfhout supplies standard platinum electrodes in the following designs: Fischer, Winkler, Wölbing and Schöniger.

Due to their high electrical conductivity and resistance to corrosion, platinum and platinum/iridium alloys are particularly suitable electrode materials. Electrodes are made of pure platinum or platinum 90% / iridium 10%. This platinum alloy is widely used for electroanalysis.

IAM Drijfhout stocks standard electrodes of the types Fischer, Winkler, Wölbing and Schöniger. Other designs can also be produced on request. For example, IAM Drijfhout has supplied the custom-made electrode below based on the simple sketch below.

Fischer electrodes – platinum 90% / iridium 10% 

Fischer electrodes consist of an inner and an outer gauze cylinder. Fischer electrodes are sandblasted to increase the wire surface which makes these electrodes suitable for rapid tests with high current densities in stirred or still electrolyte solutions.

Winkler electrodes – platinum 90% / iridium 10% 

Winkler electrodes consist of a slit gauze cylinder containing a concentrically wound wire spiral. It is most suitable for applications such as electrogravimetric identification of copper (Cu) and zinc (Zn).
