VersaSTAT 4 Potentiostat Galvanostat

• As of August 1st, 2018, the VersaSTAT 4 includes the max current capability to ±2A.
• 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 for impedance analysis over the frequency range 10µHz to 1MHz
• VersaStudio software is included with all VersaSTAT 4 systems

The VersaSTAT Series consists of the VersaSTAT 4, VersaSTAT 3F and VersaSTAT 3.

This family of instruments combines our option-based hardware and software platforms to create the most popular line of potentiostats.  Introduced for the majority of researchers doing typical electrochemical experiments, this entire series gained a key improvement in 2018.  As of August 1st, 2018, all VersaSTAT models have ± 2 Amp capability standard.  Users can now study larger samples at faster rates.

Hardware and software upgrades further extend the value of the VersaSTAT Series.  The dynamic current range on all VersaSTATs can be boosted up to 20 Amps... and can be scaled down by 1000x to 4 pA range (122 aA resolution) with the VersaSTAT-LC.  Electrochemical Impedance Spectroscopy (EIS) capability as well as DC techniques functionality can be added to the VersaSTAT Series through upgrade codes, without returning the instrument to the factory or service centers.

VersaSTATs operate within the VersaStudio software package.  Introduced in 2007, this software is the data acquisition program for all Princeton Applied Research potentiostats, including single channel and multichannel designs.  VersaStudio has dedicated techniques for most standard electrochemical experiments.  This includes actions common in energy, physical electrochemistry and corrosion applications.

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.

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