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.
