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.
