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.
Configurable
Nexus comes in different configurations:
- optional EIS/FRA module with maximum frequency of 1 MHz
- optional BiPotentiostat module for second WE
Standard included
Carrying padded bag containing:
- High quality, double shielded cell cable with
2 mm banana connectors for Working, Sense, Counter, Reference electrode and Ground - Chassis ground cable with croc clip (4 mm)
- Hardware Sync Link cable
- Crocodile clips
- Calibration report
- Dummy cell
- USB cable and Ethernet cable
- Manual and Quick Start document
- PSTrace software for Windows
- iR-compensation (ohmic drop compensation) module
- Second Sense lead cable
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.

EmStatMUX8-R2
Read moreUSB powered potentiostat with integrated multiplexer
- potentiostat with integrated 8 channel multiplexer
- potential range: ± 3V or ± 4V
- compliance voltage: ± 5V or ± 8V
- current ranges: 1 nA – 100 mA
- maximum current: ± 100 mA
With the EmStat3MUX8-R2 you can connect arrays or other setups made of up to eight working electrodes in two or three electrode cell types. If more channels are required, one or more MUX-R2 can be stacked to the EmStatMUX8-R2 for a total of up to 128 channels.
The potentiostat is controlled as well as powered by USB and is used with PSTrace. The MUX8-R2 can sample different cells at a rate of 25 ms/cell. Usually a method needs to be finished to switch the cell but the fast sampling per cell makes it possible to measure time depending techniques, e.g. chronoamperometry, practically simultaneously. Via the script window of PSTrace it is also possible to perform a different experiment on each of the channels sequentially.

Cell connections
There are four ways to connect your sensor. These sensor connections are quoted separately.
- Option A: Double shielded sensor cables with 2 mm banana connectors. The 2 mm banana connectors are compatible with standard croc clips (they will be included in the quotation as optional).
- Option B: High-density cable that terminates in ferrules
- Option C: Connection (Screw) Terminal to assemble your own wires.
- Option D: Screen Printed Electrode Connector
Each of these connection options can be used to connect 4 channels. When you add the EmStatMUX8 in the quotation basket we will make sure to include two units of the selected connection option so you can connect all 8 channels to the electrochemical cells.

USB Potentiostat Galvanoplot
Read moreUSB Potentiostat Galvanoplot is a super small, low-cost and affordable device suitable for dedicated volume applications, which is optimized for screen-printed sensor and biosensor applications. It can be used in many other research areas and with other electrochemical sensors, for corrosion measurement, battery and super-capacitors or fuel cells.
It is capable of performing all common Amperometric and Voltammetric electrochemistry protocols (CA, LSV, CV, DPV, NPV, SVW, GAL) and can be used with three electrode (WE/RE/CE) and two electrode (WE/RE-CE) setups. Plug the device directly into an Android mobile device through OTG port for a true on-site analysis experience. It is possible to choose from two types of interfaces allowing direct insertion of the BVT SPE sensors or the use of 3 classical electrodes with 2 mm banana plugs (WE, RE, CE).
