The Zennium electrochemistry workstation is the original modular electrochemical workstation introduced by Zahner to create the Zennium family of research instruments. It was developed using Zahner's decades worth of experience in producing high-precision electrochemical workstations
The Zennium has all of the hardware necessary to run as a potentiostat / galvanostat and a frequency response analyzer (FRA) unit with a frequency range up to 4 MHz at ±2.5 A and at a compliance voltage of ±14 V. With a standard input impedance of 1 TΩ || 5 pF the workstation is suitable for a wide range of electrochemical tasks.
Please review the product specifications to the right for specific details about hardware capabilities. Click the "+" to the right of the different hardware categories to review them.
The electrochemical measurement capabilites of the Zennium workstation can be extented by adding up to four 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, the Zennium electrochemical workstation can be expanded in a wide variety of ways to provide even more advanced measurement methods and allows for practically any electrochemical research requirement, no matter how complex.
The many different expansion tools available to install onto the Zennium makes it, and other members of the Zennium family of products, uniquely capable to add features as the scope of our customers' research expands.
Some examples of the add-ons available include:
Each Zennium 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.
