MultiEmStat4
The MultiEmStat4 is a compact Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS) with 8 or 12 channels. The MultiEmStat4 comes in two versions; the Low Range version is great for applications that require a low current range down to 1 nA, whereas the High Range version is very suitable for applications that need a maximum current of 200 mA.
The MultiEmStat4 is controlled with MultiTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.
- Available with 8 or 12 channels
- FRA / EIS: 10 μHz up to 200 kHz
- Potential range: ±3 V (LR) or ±6 V (HR)
- Max. current: ±30 mA (LR) or ±200 mA (HR)

Always a backup
The MultiEmStat4 is equipped with 500 MB internal storage memory on each channel for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the MultiTrace software. Your data is always with your instrument wherever you take it.
Synchronizing channels in Synched mode
By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiEmStat4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement.
Specifications
The MultiEmStat4M is available in two versions: the LR (Low Range) and HR (High Range) version.

- Bi)Potentiostat/ Galvanostat/ Impedance analyzer
- FRA / EIS: 10 μHz up to 1 MHz
- 11 current ranges: 100 pA to 1 A
- Dual EIS with second sense electrode
- Script your experiments using MethodSCRIPT
- Use with PSTrace software for Windows
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

- 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.

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.
