C3 Electrode
Our C3 Electrode is a disposable electrode developed using a uniform and pure carbon film deposited directly onto alumina substrates via chemical vapor deposition (CVD). The device consists of a pristine carbon-based working and counter electrode, and an Ag/AgCl reference electrode.
The capabilities of our C3 electrode include high chemical stability to support use with aqueous solvents, no pretreatment requirements, scratch resistance, low electrical resistance, wide electrochemical potential window, biocompatibility, and chemical inertness.
Compared to traditional screen-printed carbon electrodes that contain binders or additives, our C3 electrode consists solely of a pristine carbon layer as its active sensing surface – making them highly sensitive, stable, and reproducible in diverse electrolyte environments.
