The Metrohm Eco Chemie PGSTAT30 is a modular potentiostat/galvanostat system for electrochemical research spanning cyclic voltammetry, impedance spectroscopy, and corrosion analysis. It delivers precise voltage and current control in both potentiostatic and galvanostatic modes, supporting three-electrode and four-electrode configurations including liquid-liquid measurements. The instrument’s modular architecture enables customization through optional current boosters, impedance modules, and specialized measurement cards to match specific experimental requirements.
