Metrohm Multi Autolab M204 Multichannel Potentiostat / Galvanostat

The Metrohm Multi Autolab M204 is a modular electrochemical test system housing four independent potentiostat/galvanostat channels in one cabinet, expandable with further modules to twelve channels. Because the channels are galvanically isolated, different techniques can run on different cells simultaneously, which greatly increases throughput in parallel formulation screening, replicate experiments and long-term cycling tests. Cyclic voltammetry, chronoamperometry and chronopotentiometry, galvanostatic charge–discharge cycling, potentiodynamic polarisation and LPR corrosion-rate determination are programmed in the NOVA software; an optional FRA module adds electrochemical impedance spectroscopy (EIS). Typical specimens include lithium-ion and sodium-ion coin cells, supercapacitor electrodes, electrocatalysts, corrosion coupons and sensor electrodes; the system suits comparative materials studies that require statistical confidence.
