  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.

  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.

   

  More information can be found through the link: https://www.palmsens.com/product/emstat4s/

   

  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.

   

  Standard included

  A standard EmStat4X includes a rugged carrying case with:

  • EmStat4X LR or HR
  • USB-C cable
  • Cell cable: high quality, double-shielded cable with 2 mm banana connectors for Working, Counter, Reference electrode and Ground, 1 meter long
  • 4 or 5 crocodile clips
  • Dummy Cell

  Also included:

  • PSTrace software for Windows (on USB drive)
  • Manual (hardcopy)
  • Quick Start (hardcopy)
  • Calibration report

  SPE Connector.GC.1 for measurements in glass

  The connector enables the use of the biosensor or electrochemical sensor based on the substrates AC1, AC4 and TS1 in glass cell TC4, TC5, TC6 or TC7.

   

  The connector enables measurement with screen printed electrodes with width 7.26 mm and standard contact pads pitch (2.54 mm).
  It is compatible with other SPE´s that use the same distance between the contact pads (2.54 mm). The cone at the connector sensor side is NJ 8/10 which enables to use the connector with any standard chemical vessels.

   

  Termination: 2 mm Banana plugs
