BiPot stands for BiPotentiostat, which is a potentiostat with two working electrodes. A bipotentiostat can use two working electrodes, one reference and one counter in the same cell. The two working electrodes can be operated and monitored exactly at the same time. Working electrode 1 performs any of the supported techniques (see below), while working electrode 2 can either have its own constant potential or follow the working electrode 1’s potential. In the latter case a potential offset can be added.
Add IR-compensation module
The resistance between the reference electrode and the double layer of the specimen can cause a significant potential drop, decreasing the applied potential where it is required. The module provides positive feedback to compensate for the IR drop between the Reference electrode and the outside of the double layer of the electrochemical cell.

Our flagship instrument, the PalmSens4, is a USB and battery powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The PalmSens4 has a large potential range (-5V to 5V or -10V to 10V) and current range (100 pA to 10 mA) with a high resolution and low noise. The economical PalmSens4 is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work. Connecting via Bluetooth guarantees a perfectly floating measurement.
Configurable
PalmSens4 comes in different configurations:
±5 V or ±10 V potential range
EIS/FRA with maximum frequency of 100 kHz or 1 MHz
High quality, double shielded cell cable with
2 mm banana connectors for Working, Counter, Reference electrode and Ground
Crocodile clips
Dummy cell
USB cable
Manual and Quick Start document
PSTrace software for Windows
Always a backup
Every PalmSens4 is equipped with an internal storage of 8 GB. This means all your measurements* can automatically be saved on-board as backup.
Measurements can be browsed and transferred to the PC easily using the PSTrace software for Windows.
* Not supported for on-device backup: EIS, MultiStep and MixedMode
PalmSens4 on-board the International Space Station
The PalmSens4 potentiostat is extremely robust and reliable and was selected for NASA expedition 63. It was launched into space on 9 April 2020 being part of a scientific experiment on-board the International Space Station.
