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 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 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).

Wölbing electrodes are a gauze cylinder which is fixed to the central rod at the top and bottom via a solid cross.
| Net (M/cm²) | 100 | 100 | 100 | 100 | 100 | 100 |
| Diameter wire (mm) | 0,25 | 0,25 | 0,25 | 0,25 | 0,25 | 0,25 |
| Cilinder – diameter (mm) | 18 | 18 | 30 | 30 | 45 | 45 |
| Cylinder – height (mm) | 40 | 40 | 40 | 40 | 50 | 50 |

| Weight (gram) | 15 | 16 | 20 | 22 | 35 | 37 |
| Design | solid | hollow | solid | hollow | solid | hollow |
Schöniger electrodes are made of U-shaped pure platinum wire mesh. Primary applications include quick tests for halogen and sulfur.
| Net (M/cm²) | 16 |
| Diameter wire (mm) | 0,75 |
| Width (mm) | 10 |
