VSP3e: tailor-made for energy research

Eight channels, +/- 1A (expandable up to 800A); Ethernet connectivity, Built-in EIS


A research-grade multichannel potentiostat/galvanostat, the VSP-3e was purpose-built to meet the demands of energy research applications. With space allocated for up to eight channels, the instrument is flexible enough to meet the demands of researchers and R&D specialists alike. And with +/- 1A (expandable up to 800A with boosters), Ethernet LAN for improved multiple user/PC connectivity and built-in EIS, the instrument is especially suited to battery research applications.


Powered by EC-Lab, the advanced, ergonomic software that has earned itself the reputation as a benchmark for potentiostat/galvanostat control software, the VSP-3e boasts a wide range of unique functionality. Only EC-Lab enables users to build and modify experiments incrementally with “modify-on-the-fly” as well as give users the choice to plan their experiment from a vast array of technical presets.


Energy-specific functionality unique to Bio-Logic includes:

  • Fast CCCV shift (constant current, constant voltage)

  • Stack mode (follow individual elements in the pack)

  • BCD (Battery capacity determination)

  • Automatic plotting for Coloumbic efficiency


A compact, upright design reduces the instrument’s footprint and saves space in the laboratory and users can choose from independent channel or multi-electrode (CE to GND mode) configurations (a feature unique to Bio-Logic potentiostat/galvanostats) opening up new scientific research opportunities and enabling users to tailor electrode configurations to their application of choice.
