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.

  • EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)

    Gone are the days with too many cables. With the EmStat4 MUX you have a potentiostat and a multiplexer in one! The EmStat4 MUX is a powerful potentiostat, galvanostat and impedance analyzer and supports all popular electrochemical techniques. Its 8 channels allow for sequential measurements, for example eight Screen-printed electrodes, or eight working electrodes in eight different  cells.  The instrument’s measurements can be highly customized using MethodSCRIPT. The 4 different cell connections available allow for many different setups. When the measurements are finished, you can easily save your results in PSTrace, or export your results to Excel. 

     

    More information could be found tought link:

    • Integrated 8-channel multiplexer
    • Supports 2-, 3- and 4-electrode setup using Sense Lead
    • Potential range: ± 3V 
    • Compliance voltage: ± 5V
    • Current ranges:  1 nA – 10 mA
    • Maximum current: ± 30 mA
    • FRA / EIS up to 200 kHz

    Two modes of operation

    • Consecutive mode: this mode switches channel when a complete measurement has finished
    • Alternate mode: this mode switches all activated channels within the specified time interval of a measurement.

    In both modes the unselected Working Electrodes can either be left floating or switched to Ground to keep the specified voltage.

    Supports a 2-, 3- or 4-electrode setup

    • Connect four electrodes per channel by using the Sense Leads. 
    • Or connect only three electrodes per channel by internally connecting all Sense electrodes to the Working Electodes in software.
    • Do you need to connect only two electrodes per channel? Combine the reference and counter electrode physically on the cable, or with a single click on the PSTrace software.

    8 to 128 channels

    Is 8 channels not enough? If more channels are required, one or more MUX-R2 can be stacked to the EmStat4 MUX for a total of up to 128 channels.

    Script your experiments!

    Via the script window of PSTrace it is possible to perform a different experiment on each of the channels sequentially. Alternatively, you can use MethodSCRIPT to fully customize your measurements per channel.

    Multichannel or Multiplexer?

    To make it easier for you to decide, if  a multiplexer or a multichannel device is more suitable for your application, we have created a short explanation of multiplexers and multichannels.

  • 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.

  • 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.

  • EmStat4T (Tailored electrochemistry through touch-controlled apps)

    The EmStat4T is a programmable handheld potentiostat with a touchscreen, which is ideal for sensor research and sensor-based applications. It offers two main modes of operation:

     

    1. Remote Control: where it functions as a conventional potentiostat, controlled directly by our PSTrace software for Windows or PStouch app for Android. These applications allow you to run measurements, view results, and perform data analysis.

     

    1. Standalone: where the instrument is controlled via its touch interface to run a wizard‑style app for electrochemical analysis. Compose custom apps easily using the Visual MethodSCRIPT Editor included in PSTrace for Windows. Apps eliminate the need for a computer, tablet, or smartphone. This makes the EmStat4T an ideal solution for point-of-care applications and field research such as environmental analysis or corrosion monitoring.
