Potentiostats for Electrochemistry

Since 1976, the German company Zahner-Elektrik is developing and manufacturing innovative high-precision instruments such as potentiostats and galvanostats for all kinds of electrochemical and photoelectrochemical applications. Our multi-disciplinary team of developers is always in contact with users and at the same time at the front line of technology development.

Potentiostat customized to suit your needs.

Zahner potentiostats can be equipped with multiple plug and play addon cards, which introduce additional analog and digital in- & output signals. This modular function makes Zahner's potentiostats very flexible and allows the possibility to customize the potentiostat to suit the needs of its users.

Remote control of IM7 potentiostat

The IM7 potentiostats can operated remotely via the zahner_link API.

The zahner_link libraries communicate with am IM7 potentiostat via WebSocket connections, exchanging JSON objects. Built with a C++ core, the zahner_link also offers Python bindings for simplified programming.

WHY US?

Our Strengths

Zweipol-Hilbert transformation

Zweipol-Hilbert transformation (Z-HIT) allows the detection of non-stationarity and mutual inductivity in the measured EIS spectrum. The limitation of Kramers-Kronig does not apply to Z-HIT which ensure a better evaluation of the measured EIS spectrum than Kramers-Kronig transformation. .

Custom Experiment Builder

The Custom Experiment Builder application in Zahner Lab enables easy implementation of extensive experimental routines by assembling basic measurement techniques as modular building blocks. Using drag-and-drop, users can combine blocks into automated sequences for repeatable electrochemical test protocols and complex experiment designs.

Intelligent multi-sine

In intelligent multi-sine measurements, multiple excitation signals are generated simultaneously. This shortens the EIS measurement time without compromising the quality of the measurement.

C in CIMPS

Zahner's CIMPS system is developed for characterizing the PEC and PV systems. The CIMPS system ensures a constant and controlled light illumination during the measurement. Ability to precisely control the light intensity during the measurements makes the CIMPS one of its kind and much better setup than traditional setups for PEC or PV characterizations.

Non-linear frequency response analysis (NFRA)

For NFRA, a large excitation amplitude for impedance spectroscopy excites both the linear and the non-linear processes. Online Fourier transformation and signal processing allow to record these linear and non-linear response signals. These non-linear responses allow further insight in to the system under investigation than EIS.

AUTOMATE YOUR EXPERIMENTS

Scripting and remote control

Zahner Script:

Simple scripts can be written to automate the measurements one after another. The user can define different conditions for the start of measurement or realize complex measurement procedures. For Thales, a manual for scripting is provided here. For Zahner Lab, the Custom Experiment Builder supports measurement automation.

Remote Control:

The Zahner's potentiostats can be incorporated in a C++ or Python lab environment and can be used as stand-alone or in multi-channel configurations. For C++ and Python, GitHub repositories with the libraries and various examples are available.
