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.

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.

EmStat4T (Tailored electrochemistry through touch-controlled apps)
Read moreThe EmStat4T is a programmable handheld potentiostat with a touchscreen, which is ideal for sensor research and sensor-based applications. It offers two main modes of operation:
- Remote Control: where it functions as a conventional potentiostat, controlled directly by our PSTrace software for Windows or PStouch app for Android. These applications allow you to run measurements, view results, and perform data analysis.
- Standalone: where the instrument is controlled via its touch interface to run a wizard‑style app for electrochemical analysis. Compose custom apps easily using the Visual MethodSCRIPT Editor included in PSTrace for Windows. Apps eliminate the need for a computer, tablet, or smartphone. This makes the EmStat4T an ideal solution for point-of-care applications and field research such as environmental analysis or corrosion monitoring.

MUX8-R2 Multiplexer
Read moreMultiplexer for 8 up to 128 cells
- Automatically switch between electrochemical cells
- Easy stacking with magnetic feet and top
- 4 different electrode or sensor configurations
- Daisy chain multiplexers, up to 128 channels!
The PalmSens series and the EmStat4X can be used to work with multiple working electrodes or a sensor array by means of a multiplexer.
The multiplexer switches between the working electrodes in the range of milliseconds.
- each MUX8-R2 multiplexer enables to work with up to eight 2- or 3- electrode systems.
- daisy chaining multiple MUX8-R2 boards (expansion up to 128 channels)
- all hardware settings are controlled by the software making it unnecessary to flick a physical switch
- LEDs to show which channel is selected
- allows to connect auxiliary input (like temperature sensor)

Connection options
The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.

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.
