  Basic electrochemical cell setup (redox.me)

  This is a stationary solution basic electrochemical cell for measurements of electrodes in a form of:

  a) rod/disc (6 mm dia.),

  b) thin film deposited on a flat substrate (using a wire clip) and

  c) membrane (using a wire clip).

   

  The working, counter, and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte. The cell chamber is available in several material variants here (glass, PTFE, PEEK)

   

  Application note:
  The reference electrode tip should be placed at the level of working electrode center. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.

   

  Specification:
  maximum electrolyte volume: 50 mL
  electrode plug diameter: 6 mm
  number of electrode slots: 3

  • Bi)Potentiostat/ Galvanostat/ Impedance analyzer
  • FRA / EIS: 10 μHz up to 1 MHz
  • 11 current ranges: 100 pA to  1 A
  • Dual EIS with second sense electrode
  • Script your experiments using MethodSCRIPT
  • Use with PSTrace software for Windows

   

  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.

  The research software PSTrace makes using the Nexus a breeze. The scripting language MethodSCRIPT gives a user full control when needed. Looking for a multi-channel instrument? Just stack multiple instruments on top of each other.

  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.

  Why choose the Nexus?

  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
  pH range: 1-12

   

  Intrastat data
  HS Code: 71151000
  Country of Origin: Sweden
  NET weight: 100 g

  Working Disk Electrode – PEEK body 6 mm dia., 70 mm long (redox.me)

  This is a Standard Working Electrode in which a disk of electrode material (glassy carbon, gold, platinum, silver, boron-doped diamond, palladium, titanium, and copper) is embedded into the PEEK body by a compressed PTFE or PEEK sleeve. It well fits aqueous and organic solvent electrolyte requirements. If you need a different disk material, please contact us.

   

  Application note
  The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol or isopropanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-ring (all included in the package). Instruction on maintenance is provided on the Electrode Polishing Kit product page. 

   

  Specification

  disk diameter: 2, 3, 4 or 5 mm
  disk length: 1.5 mm for BDD, 3 mm for the rest
  body material: PEEK with PTFE or PEEK sleeve
