EmStat4R

The EmStat4R delivers desktop performance in a rugged enclosure. The EmStat4R is a portable Battery or USB-powered Potentiostat, Galvanostat, and optional a Frequency Response Analyzer (FRA) for Electrochemical Impedance Spectroscopy (EIS).

The EmStat4R is great for applications that require low currents, from 30 mA down to picoamps, such as sensor applications. The EmStat4R is controlled with PSTrace for Windows, the Android app PStouch, or you can write your own MethodSCRIPT and control it from any platform or operating system.

EmStatMUX8-R2
USB 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.

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.

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.
