Product description

Wide application range: 

The XP20 is well suited for applications requiring a high current and high voltage compliance such as electrolysis, and fuel cell applications. The XP20 is capable of ±20A/±20V.

Complete solution: 

The XP20 offers a complete package, all the standard electrochemical techniques are included. The XP20 also has an integrated  high-performance Frequency Response Analyser for EIS measurements from 10µHz to 500kHz. All measurement and dataprocessing software is included (for Windows based PCs).


The maximum current or potential of the instrument can be defined in the software by the operator. Thus valuable samples may be protected, and unsafe situations prevented.


Multiple analog and digital input & output ports are available for monitoring & control of peripheral equipment. This functionality is fully integrated in the software.


The XP20 can be expanded with a wide variety of options and modules, including True Linear Scan generator, various power boosters, and multiplexer.


  • Automatic current range selection: 100pA to 10A/1mV to 20V
  • Automatic variable noise filter and potentiostat/galvanostat stability settings
  • Simultaneous acquisition of current/potential
  • Real time data display up to 3,000 pnts/s. Acquisition up to 300,000 pnts/s is stored in instrument memory
  • Applicable scanrates: 1µV/s to 10,000V/s
  • Minimum interval time: 3.33µs (0.125µs resolution)
  • Result optimisation by automated tuned filters, gain amplifiers and DC-subtraction


The XP20 is controlled via Ivium’s own IviumSoft. This versatile, yet intuitive software, allows instrument control, data management and analysis, peripheral instrument control, etc. IviumSoft can also interface with and be controlled from LabVIEWTM, C++, Delphi, etc. A full suite of IviumSoft is included as standard with each instrument.
