  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)

  Mini RCE.GEL.L60.C1 Miniature reference argentochloride gel electrode

  Miniature 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.

  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.

  AC1.GP. Electrochemical sensor with a working electrode of guaranteed purity

  Basic amperometric three-electrode sensor with patented structure made by thick film technology.

   

  Dimensions: 25.40 mm x 7.26 mm x 0.63 mm

  WE material: gold, platinum, silver, copper, iron, nickel, cobalt, chromium, tantalum, irridium, rhenium, magnesium, palladium, zirconium and others

   

  *Selection of sensor electrode materials other than those listed above is possible upon agreement with the customer.

   

   

  The sensor is made on a corundum ceramic base. Working, reference and auxiliary electrodes are applied to this surface. Working, reference and auxiliary electrodes are made of different materials. At the end of the sensor there is a contact field that is connected to the active part by silver conductive paths that are covered with a dielectric protective layer. The working electrode of the sensor with a diameter of 2 mm is made of a material of guaranteed purity of up to 99.99 % depending on the selected material– standard layer thickness 0.0125 mm.

   

   

  We also offer a working electrode made of polished gold AC1P.W*.R*, with homogenous surface with roughness less than 1 µm.

   

  We also offer activated graphite sensors on customer request.
