  • MultiPalmSens4

    Multi-channel Potentiostat / Galvanostat / Impedance Analyzer

    • 4 to 10 channels available in different configurations
    • FRA / EIS: 10 μHz up to  1 MHz
    • 9 current ranges: 100 pA to 10 mA
    • potential range: ±5 V or  ±10 V

     

    The MultiPalmSens4 is a flexible multi-channel potentiostat, galvanostat and impedance analyzer which you can fully tailor to your requirements and budget. The MultiTrace software allows for using each channel individually or simultaneously or running a sequence of automated tasks on each channel. Each channel provides an additional auxiliary port for controlling peripherals or monitoring temperature or other analog signals.

     

    More information can be found through the link: https://www.palmsens.com/product/multipalmsens4/

     

    Configure your ideal multi-channel potentiostat

    Each channel can be configured with:

    • ±5 V or ±10 V maximum potential range
    • EIS/FRA with maximum frequency of 100 kHz or 1 MHz
    • Bipotentiostat module for second WE
    • iR-Compensation
    • Galvanic isolation

     

    Always a backup

    Every channel of the MultiPalmSens4 is equipped with 8 GB storage space. This means all your measurements* can automatically be saved on-board as backup.
    Measurements can be browsed and transferred to the PC easily using the MultiTrace software for Windows.

     

    Synchronizing channels in Synched mode

    By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiPalmSens4 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.

  • 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.

  • 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.

    Versatile

    Our high-end instrument, the Nexus, is a Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The Nexus has a large potential range (-12V to +12V) and current range (100 pA to 1 A) with a high resolution and low noise.

    Configurable

    Nexus comes in different configurations:

    • optional EIS/FRA module with maximum frequency of 1 MHz
    • optional BiPotentiostat module for second WE

    Standard included

    Carrying padded bag containing:

    • High quality, double shielded cell cable with
      2 mm banana connectors for Working, Sense, Counter, Reference electrode and Ground
    • Chassis ground cable with croc clip (4 mm)
    • Hardware Sync Link cable
    • Crocodile clips
    • Calibration report
    • Dummy cell
    • USB cable and Ethernet cable
    • Manual and Quick Start document
    • PSTrace software for Windows
    • iR-compensation (ohmic drop compensation) module
    • Second Sense lead cable
     

    S2 and BiPot

    Nexus includes a Second Sense lead (S2) and an optional BiPotentiostat (BiPot) module.

    S2 – Additional voltage (potential) measurement point

    BiPot – Independent second working electrode for simultaneous current measurement

    These two features are independent and serve distinct purposes:

    • S2 (Second Sense Lead)
      S2 acts as an additional voltage-sensing input, with the same specifications as the main reference electrode. It measures the potential at a specific point in the cell and, because the current at that point is known, it can also be used to calculate impedance.
    • BiPot (BiPotentiostat Module)
      The BiPot module introduces a second working electrode (WE2), operating versus the same reference and counter electrodes as the main channel. In BiPotentiostat mode, both working electrodes (WE1 and WE2) are recorded simultaneously. WE2 operates in potentiostatic mode, meaning it can independently control its potential and measure its current.
