Overview

The PARSTAT 4000 is the latest model of high-end potentiostat/galvanostat offered by Princeton Applied Research. It is the ultimate electrochemical research system, boasting superior specifications for virtually any  electrochemical application where a single-channel potentiostat/galvanostat/FRA is needed.

The PARSTAT 4000 is a perfect example of how customer feedback advances design. The PARSTAT 4000 combines the flexibility, versatility, and reliability of the extremely popular VersaSTAT series with the broad specification range and experimental capability of the PARSTAT 2273 to create the most powerful potentiostat/galvanostat/EIS analyzer that Princeton Applied Research has ever offered.

  • +/-4 A current max (20A Booster Option) over 13 current ranges (40pA-20A)
  • +/-48V compliance (+/-10V reference) voltage
  • 1.2fA current resolution on lowest 40pA range (2.5aA with low current option)
  • 1µs data sampling capability with 4M point onboard data buffer
  • Isolated (floating) lead capability for grounded electrode/cell applications
  • Unwanted noise removal via selection of 5 analog E and I filters, as well as available 50Hz and 60Hz notch filters for power noise reduction.

The PARSTAT 4000’s hardware is capable of +/- 10V scan/pulse range, +/-4A compliance current, and built-in EIS measurements up to 5MHz. The interface to the computer is Universal Serial Bus (USB), and the system is controlled via VersaStudio software.
