VersaSTAT 3 Potentiostat Galvanostat

VersaSTAT3 - Front Panel
The VersaSTAT 3 is an optioned-based platform that provides both standard core functionality and the ability to expand the range of measurements.
This versatile potentiostat and galvanostat addresses many different applications including Corrosion, Energy Storage, Sensors, Nanotechnology, and Physical Electrochemistry.

  • As of August 1st, 2018, the VersaSTAT 3 includes the max current capability to ±2A.  This expands its capability to test larger samples at higher rates
  • High current boosters up to 20A for battery, fuel cell, or electroplating applications
  • Excellent current measurement resolution for corrosion, coatings, and micro-electrode analysis
  • An internal frequency response analyzer option that provides impedance analysis over the frequency range 10µHz to 1MHz

VersaStudio software is included with all VersaSTAT 3 systems and users can select from the different groups of techniques that are available:

Energy providing charge-discharge curves (including CC-CV) for Capacity-vs-Cycle Number or Coulombic Efficiency as well as dedicated techniques such as Constant Power, Constant Resistance and Potentiostatic / Galvanostatic Intermittent Titration Technique (PITT, GITT)

Voltammetry providing fundamental electrochemical techniques such as Cyclic Voltammetry, Chrono-techniques.  The Advanced Voltammetry techniques also include Pulse Voltammetry methods.

Corrosion providing multiple corrosion analysis techniques, including the most common ASTM standards such as Linear Polarization Resistance (LPR, ASTM G59), Tafel (ASTM G5), Cyclic Polarization (ASTM G61), etc.

Impedance may be added to any system to provide Electrochemical Impedance Spectroscopy techniques
