Glassy Carbon has a quite unique structure. This material contains random combination of basal plane and edge plane. The figure, at the right, shows the model illustration introduced by G. M. Jenkins and K. Kawamura. It becomes an outstanding material, which can be used for the electrode in an analytical chemistry domain as electrochemical
measurements, detection of high-speed liquid chromatography, biosensor and others.

Glassy carbon electrode with Teflon ring
• Conventional electrode
• Wide over-potentials for oxygen and hydrogen evolution
• Chemically stable
• Improved to facilitate the handling to obtain a chemically modified electrode
For the GCEt Glassy carbon electrode, a Teflon spacer was included between the PEEK insulation and glassy carbon disk. For the property of the material, it will avoid that the sample spreads, to get the chemically modified surface.
