Zennium E4

The Zennium E4 electrochemistry workstation, manufactured by Zahner, is the most economical of all the Zennium workstations. Despite the lower price point, it retains a very high degree of hardware performance and is well-suited for many applications. The Zennium E4 is designed for customers requiring more precision and features than the Squidstat platform can deliver.


As with all of the other Zennium workstations, the Zennium E4 includes a potentiostat / galvanostat and a frequency response analyzer unit (FRA) for running electrochemical impedance spectroscopy (EIS) up to 4 MHz with a maximum current of ±2 A and a ±12 V scan range.

Special measurement techniques and probes guarantee an ultra high accuracy and a minimal interference with the sample cell being examined. The Zennium E4 can be easily switched from grounded to floating operation. The primary drawback of the Zennium E4 is that there are no expansion slots available to install the add-on cards compatible with other Zennium models.


Each Zennium E4 purchase comes bundled with Zahner's Thales XT software package enabling users to run all standard electrochemical methods and more with ease. A summary of the different methods the Zennium is capable of running are availabie in the dropdown menu to the right.
