Bi-potentiostat / Bi-galvanostat Electrochemical Workstation

MSE Supplies offers electrochemical workstation (bi-potentiostat / bi-galvanostat) with built-in EIS model. It has two sets of built-in independent potentiostat /galvanosta. Each set provides full electrochemical techniques (EIS included). Experiments can be conducted simultaneously in each channel. Additionally, the two channels can jointly complete experiment of two-working electrode system (RRDE and hydrogen diffusion). With high performance in stability and accuracy with advanced hardware and well-functioned software, it is a comprehensive research platform for corrosion, batteries, electrochemical analysis, sensor, life science and environmental chemistry etc.

Customers from Australia, South Korea, India, Turkey and Kazakhstan please contact Corrtest directly.
