Precious Electrodes

Electrodes made of platinum and platinum alloys are known for their high electrical conductivity and resistance to chemical attack. Electrodes are made of pure platinum or platinum/iridium 90/10. This material will ensure mechanical stability and make your electrode application as easy as possible.

The different electrode designs:

Schoeniger Electrodes

Schoeniger Electrodes are made of a pure platinum wire mesh bent into a U-shape. This kind of electrode is primarily used for the rapid determination of halogens and Sulphur.

This design consists of a platinum wire mesh bent into a U-shape. It is used mainly for the rapid determination of halogens and Sulphur.

 

Fischer Electrodes

Fischer Electrodes are sandblasted 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 needs.

Woelbing Electrodes

Woelbing Electrodes contain a gauze that 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.

In this electrode, the gauze is fixed stably to the central rod at the top and bottom via a solid cross.

Winkler Electrodes

Winkler Electrodes are sandblasted 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 Winkler electrodes, we can supply each electrode sand-blasted, depending on your individual need.

This design consists of a slit gauze cylinder in which a wire spiral is concentrically positioned.

Spiral electrode is a type of Winkel electrode.
