VersaSTAT 3F Potentiostat Galvanostat

VersaSTAT 3F - Potentiostat Galvanostat
The VersaSTAT 3F shares similar specifications to the VersaSTAT 3 (10µs data acquisition) and the VersaSTAT 4 (4nA lower current range, enhanced filtering options) the VersaSTAT 3F was designed specifically to operate with other potentiostats or earth-grounded cells.

The "F" in the VersaSTAT 3F name is for "Floating," a term used to describe the electrical isolation of the systems electrode leads and rear panel connectors from the earth ground. In floating mode, the internal ground of the VersaSTAT 3F (as well as the cell leads and external connections at the rear panel) is allowed to float with respect to earth grounded cells. Examples or earth grounded cells include autoclaves, strain apparatus, storage tanks and pipelines, and additional electrodes connected to a separate potentiostat that is not floating.

The VersaSTAT 3F was designed to operate in either a "normal" mode (same mode as V3 and V4 models) or a "floating" mode, selectable in the operating software. In addition to the mode selections, the VersaSTAT 3F also provides additional filters that could be required with some cells in order to enhance the signal to noise. A special "Notch Filter" for those frequencies associated with line power (50/60Hz) are available as needed.

  • Capable of "Floating" for operation with other potentiostats, grounded cells and electrodes
  • Specialized filters for float mode operation for enhanced signal/noise ratio at 50/60 Hz
  • Analog filter selections on current and voltage channels for superior signal/noise measurements (NONE, 200 kHz, 1 kHz, 100 Hz, 10 Hz, 1 Hz)
  • ±2 A/±10V polarization range as standard
  • An internal frequency response analyzer option that provides impedance analysis over the frequency range 10µHz to 1MHz
  • Additional bandwidth filtering options for greater stability on capacitive cells
  • Easy-to-use VersaStudio software included
VersaStudio software is included with all VersaSTAT 3F 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
