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
optional BiPotentiostat module for second WE

Standard included

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

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.

EmStat4X
The EmStat4X delivers high performance in a small footprint. The EmStat4X is a small battery and USB-powered Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS).

The EmStat4X Low Range (LR) version is great for applications that require measuring low currents down to picoamps, like (bio)sensor research. The High Range (HR) version is very suitable for applications that need a maximum current of up to 200 mA. The EmStat4X is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.

More information can be found through the link: https://www.palmsens.com/product/emstat4s/

The EmStat4X LR and HR features include:

Fast EIS support: for running fixed-frequency EIS measurements at a very low interval of around 1 ms.

Auxiliary Port: for connecting to a MUX8-R2 multiplexer, temperature sensor, pH sensor, stirrer control, triggering and more.

iR compensation: to compensate for the iR drop between the Reference electrode and the outside of the double layer of the electrochemical cell.

Bluetooth: for a wireless connection to a PC, smartphone or tablet

11.1 Wh battery: for more than 8 hours of continuous measurements (typical with the LR).

Small borderless display: showing the state of the battery and connectivity.

Two versions

The EmStat4X comes in two different versions:

Low Range: for lower currents and potentials (±30 mA / ±3 V applied / ±5 V compliance)

High Range: for higher currents and potentials (±200 mA / ±6 V applied / ±8 V compliance)

Both versions can be configured with optional EIS/FRA up to 200 kHz.
See specifications for a detailed comparison between the LR and HR.

Always a backup

The EmStat4X is equipped with 500 MB internal storage memory for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the PSTrace software for Windows. Your data is always with your instrument wherever you take it.

Standard included

A standard EmStat4X includes a rugged carrying case with:

EmStat4X LR or HR

USB-C cable

Cell cable: high quality, double-shielded cable with 2 mm banana connectors for Working, Counter, Reference electrode and Ground, 1 meter long

4 or 5 crocodile clips

Dummy Cell

Sensit BT

Handheld and wireless dual-channel potentiostat

Capable of EIS up to 200 kHz
Built around the EmStat Pico module
Potential range -1.7 to +2 V
Current ranges 100 nA – 5 mA (max ±3 mA)
Can be used without PC or smartphone connection

The Sensit BT is ideal for electrochemical sensor applications. The Sensit BT connects via Bluetooth to your smartphone or tablet and controlled via the Android app PStouch. You can use the USB-C port to charge the Sensit BT or connect to a classic USB port on your PC and control the Sensit BT via our PC software PSTrace.

The Sensit BT supports most common electrochemical techniques, including Cyclic Voltammetry, Square Wave Voltammetry and Impedance Spectroscopy (FRA/EIS).

Electrode connections	RE, WE, CE	Connectors	2 mm banana
Allowed sensor thickness	Between 0.1 mm and 0.8 mm	Electrode connections	RE, WE, WE2, CE
Maximum sensor width	11 mm

Dual-channel and Bipotentiostat

The Sensit BT.SPE can be used for running sequential measurements on two different Screen-Printed Electrodes (SPE’s) each with their own Reference, Counter and Working electrodes.

The second channel can also be used in Bipotentiostat mode, functioning as second Working Electrode versus the Reference and Counter electrode of channel 1. Both working electrodes are recorded simultaneously in the Bipotentiostat mode.

The Sensit BT.SNS has a lead connected to the WE of channel 2 and can be used out-of-the-box for BiPotentiostat measurements.

On-board data storage

The Sensit BT is equipped with 500 MB internal storage memory.

Save measurements on-board as a backup. Or pre-program the device with a script and use the trigger button to run and store measurements: no need to connect a PC or smartphone. Browse and transfer all internally stored measurements back to the PC easily using PSTrace for Windows.

SPE Connector.GC.1 for measurements in glass

The connector enables the use of the biosensor or electrochemical sensor based on the substrates AC1, AC4 and TS1 in glass cell TC4, TC5, TC6 or TC7.

The connector enables measurement with screen printed electrodes with width 7.26 mm and standard contact pads pitch (2.54 mm).
It is compatible with other SPE´s that use the same distance between the contact pads (2.54 mm). The cone at the connector sensor side is NJ 8/10 which enables to use the connector with any standard chemical vessels.
