  • SDC Scanning Droplet Cell

    • SDC technique confines the electrochemical measurement to the small droplet of electrolyte, defining the area of the electrode/electrolyte interface.
    • Samples can be investigated without cutting the sample or subjecting areas to different electrolyte exposure times.
    • Capable of running both constant bias/swept position plots for data maps and fixed-position/ dynamic signal plots for Cyclic Voltammetry, Tafel, EIS, etc.
