MUX8-R2 Multiplexer
Multiplexer 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.

Mini RCE.GEL.L60.C1 Miniature reference argentochloride gel electrode
Read moreMiniature reference argentochloride gel electrode is designed for potentiometric measurements in connection with Miniature ion selective electrodes for potentiometric measurements of Chloride ions, Sodium ions, Calcium and Potassium ions concentration in aqueous solutions following prior calibration.
The conductive connection of the internal electrolyte (KCl gel) enclosed in a plastic tube is mediated by a porous frit.
Maintenance-free electrode – no need to top up the internal electrolyte (KCl gel).
Electrodes are applicable to all commonly used measuring apparatus, with input resistance of at least 1012 Ω.
Possibility of integration with a FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring – possible automation and continuous measurement.

EmStat4S
Read moreThe EmStat4S delivers desktop performance in the palm of your hand. The EmStat4S is a portable USB-powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4S is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.
More information can be found through the link: https://www.palmsens.com/product/emstat4s/
Versions
The EmStat4S comes in two different versions:
- Low Range: for lower currents and potentials
- High Range: for higher currents and potentials
Both versions can be configured with optional EIS/FRA with a maximum frequency of 200 kHz.
Main differences between the EmStat4S Low and High Range Potential range ±3 V ±6 V Max. compliance voltage
±5 V ±8 V Current ranges 1 nA to 10 mA (8 ranges) 100 nA to 100 mA (7 ranges) Max. current ±30 mA ±200 mA Electrode connections WE, RE, CE and ground,

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.
