ZAHNER ZENNIUM pro

Electrochemical Workstation

The all-purpose instrument

Since 1976, ZAHNER-elektrik is producing Electrochemical Workstations at the edge of technology. The systems are highly praised for their exceptional accuracy, flexibility and reliability. Now, the ZAHNER R&D-team launched a new generation of Electrochemical Workstations including the ZENNIUM pro defining the Goldstandard in electrochemical instrumentation.

If you go through the technical specifications below you will find outstanding features and data like

32 bit converter resolution for exceptional DC accuracy
Electrochemical Impedance Spectroscopy (EIS) frequency range from 10 µHz to 8 MHz
HDP technology with 24 bit AC resolution for highest dynamic accuracy
ADF technology (optional) for extremely fast CV up to 10 kV/s with continuous slopes for outstanding CV performance
Compliance voltage up to ±28 V
Software switchable compliance voltage for minimum noise, optimum sample safety and energy efficieny
DC voltage ranges ±5 V and ±15 V software controlled perfectly matching the requirements of Lithium battery research
AC amplitude 0 - 2 V and 0 - 6 V with 18 bit resolution
Modular concept for high flexibility and expandability
Floating / grounded mode switchable for measuring on a wide range of objects

The ZENNIUM pro comes with the new THALES XT Software Suite providing features such as highly flexible Windows®-conform online visualization and intuitive offline data analysis.

The ZENNIUM pro is a modular electrochemical workstation including a potentiostat / galvanostat and a frequency response analyzer (FRA) unit with a frequency range up to 8 MHz at ±3 A and at a compliance voltage of up to ±28 V. With an input impedance of more than 10 TΩ || 5 pF the workstation is suitable for a wide range of electrochemical tasks.

The electrochemical measurement capabilites of the ZENNIUM pro workstation can be extented by adding up to five additional plug-in cards such as TEMP/U or EPC42. For example, the latter makes it possible to control up to four additional external devices such as power potentiostats of the PP/XPot-series (boosters) or electrical loads of the EL-series. Thus, our ZENNIUM pro electrochemical workstation is able to provide even more advanced measurement methods and allows us to satisfy any of your electrochemical research requirements.
