Building on PalmSens’ legacy of providing top-tier solutions for accurate low-current measurements, Nexus delivers an ultra-low-noise performance that exceeds even our existing portable devices, while also supporting measurements up to 1 Ampere.
Versatile
Our high-end instrument, the Nexus, is a Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The Nexus has a large potential range (-12V to +12V) and current range (100 pA to 1 A) with a high resolution and low noise.
The research software PSTrace makes using the Nexus a breeze. The scripting language MethodSCRIPT gives a user full control when needed. Looking for a multi-channel instrument? Just stack multiple instruments on top of each other.

Nexus comes in different configurations:
- optional EIS/FRA module with maximum frequency of 1 MHz

S2 and BiPot
Nexus includes a Second Sense lead (S2) and an optional BiPotentiostat (BiPot) module.
S2 – Additional voltage (potential) measurement point
BiPot – Independent second working electrode for simultaneous current measurement
These two features are independent and serve distinct purposes:
- S2 (Second Sense Lead)
S2 acts as an additional voltage-sensing input, with the same specifications as the main reference electrode. It measures the potential at a specific point in the cell and, because the current at that point is known, it can also be used to calculate impedance. - BiPot (BiPotentiostat Module)
The BiPot module introduces a second working electrode (WE2), operating versus the same reference and counter electrodes as the main channel. In BiPotentiostat mode, both working electrodes (WE1 and WE2) are recorded simultaneously. WE2 operates in potentiostatic mode, meaning it can independently control its potential and measure its current. Refer to our BiPotentiostat article to check which techniques are available when using this mode.
