HEKA PG 618 USB Ultra Bipotentiostat SECM

The Specialist for Scanning Probe Microscopy

Order Number: 895144

The PG 618 USB is a bipotentiostat/bigalvanostat that features two different amplifier boards. The first amplifier board has a compliance voltage of ±12 V and a working current range from 20 nA to 100 mA. The second amplifier board has a compliance voltage of ±5 V and a working current range from 5 pA to 2 µA. Providing such a huge current range makes the PG 618 USB unique in the market. In the PG 618 USB both working electrodes can be controlled independently from each other. Further, having two working electrodes available allows to investigate redox chemistry in a ring-disc configuration.
