Working electrodes

This is where it all happens

Working electrodes are of utter importance because this is where everything that interests the electrochemist will happen. A large offer of working electrodes are available with a very wide range of size and materials.

9 metals are available: Carbon, Pt, Au, Ag, Pd, Ni, Cu, Fe, BDD (Boron-doped diamond), as well as empty electrodes to host carbon paste that is also available.
Different sizes are available from 5 mm down 10 µm.


A polishing kit is also available.



Note the UME electrode dedicated to SECM are available here:


More details are given in the specifications section.

Specifications and ordering information


These working electrodes are all made of a PEEK isolation body.

Working electrodes maintenance

To refresh the surface of the electrode we recommend to polish the electrode before each measurement.
