NEW Bipotentiostat / Dual Channel Potentiostat

The PARSTAT 3000A-DX is both:

  • A bipotentiostat capable of independently controlling two working electrodes in a single electrochemical cell, with hardware synchronised start.
  • AND a 2-channel potentiostat with industry leading specifications; Control two entirely separate electrochemical cells.

This new instrument has the same compact footprint as the PARSTAT 3000A. It includes both a high voltage and a high current channel, as well as EIS functionality on both channels.

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

As a true bipotentiostat, the PARSTAT 3000A-DX controls the signal and measures the response of two different working electrodes in the same cell, with separate or shared reference and counter electrodes.

Rotators, RRDE electrodes and associated accessories are also available for a complete RRDE setup.

RRDE potentiostat experiment

Au/Au RRDE collection efficiency experiment


The PARSTAT 3000A-DX uses Princeton Applied Research’s popular VersaStudio software:

  • Easy to use, flexible experimental set-up
  • Straightforward data comparison
  • Useful data analysis and fitting routines

Each potentiostat channel has full access to VersaStudio’s complete range of electrochemical techniques, including:

  • Voltammetry
  • Corrosion
  • Energy
  • Impedance
  • Advanced Actions

New RRDE Action

The new RRDE Action is designed for rotating ring disk electrode experiments. The rotation rate can be controlled, and various techniques can be selected independently for each channel including:

  • Cchronoamperometry
  • Chronopotentiometry
  • Ramp / staircase cyclic voltammetry
  • Linear scan voltammetry.

Plot disk and ring current against disk potential in a single graph, so the data can be interpreted easily.
