Electrodes
Counter electrodes
We offer several materials and size for the counter electrodes. When choosing the counter electrode care must be taken in the electrode area, which should not be lower than the working electrode area, otherwise the counter becomes a limiting factor for the flowing current. The counter electrodes are divided in two categories: small and large, the same way the reference electrodes or the cells are divided.

| Counter electrode selection | |
| The counter should not be the limiting factor for the electron transfer, so the surface area of the counter electrode should be higher than the surface area of the working electrode. |
