Arbin’s Multi-Channel Potentiostat/Galvanostate (MSTAT) system is designed for high performance electrochemical research of battery materials and advanced battery cell testing. Each channel is an independent potentiostat/galvanostat and gives users full control of test profiles and data logging to offer unmatched flexibility.  No other potentiostat manufacturer offers range of channels, voltage, current, and feature-set as Arbin. Researchers and startup companies who begin working with Arbin can continue to use our battery testing systems and software solutions as they grow and scale up.  

The Arbin MSTAT provides true bipolar circuitry to ensure cross-zero linearity with no switching time between charge and discharge. MSTAT hardware provides both digital and analog voltage control. Digital control maximizes the safety of battery cycling and can handle dynamic device resistance, while analog control enables the fast response and stability necessary for electrochemical applications.

This product consists of independent potentiostat/galvanostat channels for testing battery materials and other electrochemical applications, and is intended to provide an economical solution for applications requiring high‐precision measurements and fast data sampling. All Arbin testing systems come with a PC pre-loaded with our MITS Pro and Data Watcher software for creating test profiles, real‐time data monitoring, and data plotting & analysis.  

Electrochemical Impedance Spectroscopy (EIS) is optionally available on all channels and is multiplexed internally.  This means you never have to change connections when performing EIS on the tester.
