  • Overview +

    PARSTAT Single Channel Family
    The PARSTAT Single Channel Family consists of the PARSTAT4000A and PARSTAT3000A.

    This series of potentiostats is defined by offering superior performance as standard.  The PARSTAT4000A and PARSTAT3000A complement each other.
    Both of these single channel potentiostats operate in VersaStudio software with all techniques available, including Electrochemical Impedance Spectroscopy up to high frequency.

    The PARSTAT4000A provides high compliance voltage and improved voltage accuracy.  
    The PARSTAT3000A provides 6-WIRE measurement and high polarization voltage.
  • Applications and Software +

    The PARSTAT 4000A stands alone in its ability to deliver high compliance voltage and wide dynamic current range, as standard, to cover a range of applications. The PARSTAT 4000A builds on PAR's history as the world-leader in DC electrochemical measurements and takes advantage of a common R/D team with Solartron Analytical, the world-leader in Frequency Response Analyzer (FRA) technology, to provide a best-in-class complete system.

    Specifically, the PARSTAT 4000A has industry-leading DC Voltage Accuracy, both Applied and Measured.  This is advantageous for all electrochemical experiments, whether operating as a potentiostat, galvanostat, or zero resistance ammeter (ZRA).  The most common research areas and techniques that benefit from this improved accuracy are:

    Energy:  Batteries (Li-ion, Li-Air, Zn-Air), capacitors, and fuel cells  -- 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 Physical electrochemistry and electrochemical sensors -- providing fundamental electrochemical techniques such as Cyclic Voltammetry, Chrono-techniques. The Advanced Voltammetry techniques also include Pulse Voltammetry methods.

    Corrosion:  Bare-metal corrosion, galvanic couples and coatings --  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.  The new hardware-based, user-selectable Stability Modes further expands the compatibility of the PARSTAT4000A with a range of electrochemical cells and samples.

    Impedance: Separation of electrochemical responses into individual contributions for improved understanding of system under test.
