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.

    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

    • 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.

  • EmStat4T (Tailored electrochemistry through touch-controlled apps)

    The 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:

     

    1. 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.

     

    1. 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.
