  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.

  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.

  The MUX8-R2 has the following connectors:

  Connector	Function
  Input	Y-cable connects to both potentiostat sensor connector and (digital) AUX
  AUX	Can be used to measure auxiliary input like temperature or pH, and to switch external hardware using two digital control lines that can be set in PSTrace
  Link	Connects to Input of next multiplexer, for daisy-chaining multiple multiplexers
  USB-C	Input for extra power when ≥3 multiplexers are daisy-chained
  Channel 1-4	Connects to sensor cables 1-4
  Channel 5-8	Connects to sensor cables 5-8

  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.
