PARSTAT 3000A-DX バイポテンショスタット/ガルバノスタット


The PARSTAT 3000A-DX from Princeton Applied Research is both a hardware synchronized bipotentiostat/galvanostat and dual channel potentiostat/galvanostat in one.  The compact design, based on the popular PARSTAT 3000A, combines 2 high performance, independent potentiostats in a single chassis.  Combine this with a hardware synchronized start and the VersaStudio software platform for a fully functional bipotentiostat that is suitable for a range of applications from mechanistic studies and electrocatalyst evaluation using a rotating ring disk electrode (RRDE) to sensor development.

Key features of the PARSTAT 3000A-DX include:

  • +/- 2 A of current and +/- 30 V polarization and compliance
  • Up to 7 MHz EIS as standard
  • 4 nA (120 fA resolution) as standard
  • 6-WIRE capability to measure an auxiliary voltage
  • Floating ground
  • Data acquisition rate of up to 1000 kS/sec (1 µs time per point) 

As a true bipotentiostat the PARSTAT 3000A-DX can control the signal and measure the response of two different working electrodes in the same cell with separate or shared reference and counter electrodes.  The floating capability and hardware synchronization of the PARSTAT 3000A-DX, along with the wide range of available techniques in VersaStudio, make for an ideal and flexible bipotentiostat/galvanostat.  Princeton Applied Research also offers rotators, RRDE electrodes and associated accessories for a complete RRDE setup.

When not used as a bipotentiostat, the PARSTAT 3000A-DX can run two asynchronous experiments on completely separate electrochemical cells.  The outstanding specifications accommodate a range of applications highlighted below.

  • +/- 30 V compliance – Corrosion analysis in low conductivity electrolyte, large surface area samples and non-aqueous electrochemistry, including ionic liquids and molten salts
  • +/-30 V polarization – Study of high voltage batteries and battery stacks 
  • Wide dynamic current range (+/- 2 A to 4 nA) – 10 current ranges allow for detection of a low concentration analyte common in electroanalytical chemistry and measurement of high currents associated with high surface area nanostructured electrodes for capacitor development
  • 7 MHz EIS – Solid-state materials analysis and measurements of equivalent series resistance (ESR) and uncompensated resistance
  • 6-WIRE – Simultaneous DC and EIS measurements of anode/cathode or single cell/complete stack
