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.

Mini *-ISE-L60.C* Miniature ion selective elecrodes
Read moreMiniature ion selective electrodes for potentiometric measurements of Chloride ions, Sodium ions, Calcium and Potassium ions concentration in aqueous solutions when used together with a reference electrode (following prior calibration) with a diameter of 6 mm and a length of 60 mm.
Specifically, these applications may include analyses for agricultural purposes, online monitoring of the representation of selected ions in water management, certain industrial areas or agriculture (hydroponic cultivation of plants) etc.
Electrodes are applicable to all commonly used measuring apparatus, with input resistance of at least 1012 Ω. The work with ion selective electrodes is time effective, requires an only small amount of chemicals, and a friendly price of measuring equipment (potentiostat with measuring method potentiometry).
Possibility of integration with a FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring – possible automation and continuous measurement.
* For this product, we recommend our customers use the Training Service from BVT.

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.
