Zahner XPOT Potentiostat



The XPOT is a low power 4-quadrant potentiostat which may be used in connection with a impedance spectrometer IM6/Zennium. The XPOT provides up to ±500 mA output current at ±25 V compliance voltage.


The XPOT potentiostat is controlled by an EPC42, a plug-in module for the Electrochemical Workstations IM6 and Zennium. Due to the built-in microprocessor each EPC42 can address up to four XPOT potentiostats. Up to four EPC42 cards can be installed in an IM6 or a Zennium. In total, up to 16 XPOTs can be controlled by one IM6/Zennium. Using the  XPOT allows parallel investigation of different objects. In such multi-cell arrangements, potentiostats which are not addressed, will hold their DC conditions. Each potentiostat will hold the control parameters from one access to the next one, so that no potential or current disturbances can occur while scanning the potentiostats. If series measurements are performed with more than one XPOT potentiostat, spectra are taken from all modules in a definable order.

The XPOT is embedded completely in the IM6/Zennium environment. Thus, all acquisition and analysis techniques that run on the IM6/Zennium can be applied with the external potentiostat as well. The installation of one or more XPOT potentiostat will upgrade your IM6/Zennium to an even more versatile multi-potentiostat electrochemical workstation.

Besides, the XPOT potentiostats can be controlled by a Windows®-PC. In this case they provide the methods Test Sampling as well as U- and I-curves vs. time. They also work as a LabView® Virtual Instrument under the LabView® software.

Furthermore, you can control the XPOT potentiostats in a mixed mode with an IM6/Zennium and a PC in parallel. Both devices can be connected and disconnected in operation.
