What makes a glassy carbon electrode a flexible option to use it as working electrode in electrochemical applications?

In general, Glassy Carbon Electrode (GCE) is the preferred working electrode in electrochemistry because of their chemical inertness, easy fabrication, high hardness, wide range potential, high electrical conductivity, low capacitance, and low current background. GCE is made of amorphous, non-graphitic carbon that has been thoroughly purified. Due to its low reactivity (high corrosion resistance) makes a flexible option for most of the electrochemical applications.
