The Metrohm Autolab PGSTAT12 is a potentiostat/galvanostat system for electrochemical research and development. It delivers precise potential and current control across potentiostatic, galvanostatic, potentiodynamic, and galvanodynamic modes, supporting three- or four-electrode configurations. The instrument combines millivolt-level accuracy with picoampere resolution, enabling sensitive electrochemical measurements from corrosion studies to battery testing and materials characterization.
