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.

FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring
Read moreThe flow cell with integrated stirring and reduced hydrodynamic noise is designed for the determination of single analyte using one miniature ion-selective electrode (ISE) and one miniature reference electrode with a diameter of 6 mm and length of 60 mm.
Rotation speed of integrated stirrer: 10-4000 rmp.
Miniature ion-selective electrodes and reference electrode were designed for integration into the flow cell for determination of Cl-, K+, Ca2+ and Na+ ions.
In flow mode, the system can operate automatically. The speed of the integrated stirrer can also be controlled by applying the corresponding voltage to the motor, connected to a stabilized source.
The flow cell with one selected ISE can be used for:
- Automatic or semi-automatic measurement of concentration of Cl-, K+, Ca2+ and Na+ ions in various solutions (following prior calibration)
- For continuous measurement of changes in concentration of Cl-, K+, Ca2+ and Na+ ions.

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.

Hanging Platinum Drop Electrode
Read moreThe Hanging Platinum Drop Electrode (HPDE) is solid phase alanogy of HMDE.
The drop of liquid Pt at 2000 °C forms a drop of Pt. The surface of HPDE has nearly ideal surface which is impossible to obtain using polishing. HPDE has also spherical symmetry which enables mathematical treatment of its response.
The material is not toxic and it is chemically stable. The only disadvantage is HPDE cleaning, which can be, however, in some cases solved by carefull insertion of the electrode tip to the flame of an alcohol burner.
Thus HPDE can be used as reference electrode for complicated electrochemical studies, where it is necessary to distinguish the analytical signal from the signal generated by surface inhomogenities.Hanging platinum drop electrode (HPDE) is designed for measurements with thermostated cell TC4, TC5, TC6 and TC9.
