  • 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:

    https://www.palmsens.com/product/emstat4-mux/

     

    • 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.

  • Sample Holder 25 mm x 25 mm (redox.me)

    The sample holder (known also as flat specimen holder) is used for holding flat, circular or square/rectangular samples. It enables contacting the sample from the front (e.g. ITO/FTO glass, Monolayer Graphene on SiC, or Boron-Doped Diamond thin film on various substrates) and from the back (e.g. metal specimen, Glassy Carbon plate, Boron-Doped Diamond plate). The default nominal aperture is 1cm2, but other value can be provided on request. The large electrical contact with Tantalum (formerly Copper) foil surface (not being in contact with an electrolyte) ensures optimal current collection by minimizing electrical resistance and unifying current distribution. The rod with electrical connection has a diameter of 6 mm, which makes the sample holder compatible with our voltammetry cells and jacketed cells, as long as it fits in. We may also provide an adapter to install this sample holder in openings larger than 6 mm dia.

     

    The sample holder elements are constructed with materials that are inert to the electrochemical system (PEEK, Fluorocarbons). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is well sealed which prevents the electrolyte to leak inside.

     

    Application note
    The sample holder is used largely for corrosion studies. It can be installed in a beaker type cell as well as in testing environments such as open water reservoirs, cans, tanks etc. It can also be used wherever it is necessary to make an electrode using a thin layer of an active material deposited on a flat substrate (conducting or insulating).

  • Platinum Coated Titanium Mesh Electrode with Holder – set of 10 pcs (redox.me)

    The metal counter (auxiliary) electrode is provided in electrochemical cell as a current sink to shunt excess current away from the reference electrode. Platinum Coated Titanium Mesh Electrode is a cheap alternative to pure Platinum Electrodes like Platinum Gauze Electrode or Metal Wire Auxiliary Electrode. Platinum coating makes this counter electrode inert under the reaction conditions and provides catalytic properties. The electrode is installed in the Basic Sample Holder (1 pcs included in the set), which allows full immersion of the electrode in the electrolyte (wet Tantalum contact). It well fits aqueous and organic solvent electrolyte requirements. Electrode size is customizable. 

     

    Application note
    The Platinum Coated Titanium Mesh Electrode is fully immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the Platinum Coated Titanium Mesh Electrode for a certain amount of time. After the process, the electrode should be washed several times with ethanol and dried under the nitrogen flow. Store the electrode in a dedicated compartment to avoid scratching. Discoloration may indicate the degradation (dissolution) of the Platinum layer and oxidation of Titanium mesh. 
    This electrode is used mainly in systems where there is a high risk of its contamination by organic or inorganic deposit during the electrochemical reaction. It is also a cheap replacement for pure Platinum electrode in electrodeposition processes.

     

    Specification
    Titanium grade: GR1
    working current: <5000 A/m2
    Platinum content: >15 g/m2
    Platinum coating thickness: 760 – 1500 nm
    mesh hole size: 3 mm x 2 mm
    mesh thickness: 0.5 mm
    electrode size: 25x25mm2, 50x50mm2, 100x100mm2, custom
