Potentiostats

Introduction

The VMP-300 multichannel potentiostat is a modular chassis with 16 slots for potentiostats, galvanostats, EIS boards, and/or booster boards. These different channels can be combined based on users’ needs, either to reach high currents or to drive multiple measurements simultaneously across all channels. EIS capability is available as an option with a wide frequency range of up to 7 MHz. Low current sensitivity can be further improved using the ultra-low current option. All multichannel potentiostats are multiple user systems. Several computers can be connected to the electrochemical workstation at the same time, thanks to BioLogic’s Ethernet LAN connection capability.
