  8/16-Channel Potentiostat for High Resolution Data Logger

  The device consists of a combination of an multi-channel potentiostat/converter (BVT Technologies) and an external USB Pico ADC high resolution data logger (Pico Technology).

   

  The data logger can be supplied in two versions: ADC-20 (20 bits, 8 channels) or ADC-24 (24 bits, 16 channels). For detailed specifications, see the attachment at the end of the document. The device allows measurements from up to 8 or from up to 16 independent channels. The basic output signal is a voltage in the range of -2.5 to 2.5 V. All channels are programmable (the output can be concentration, temperature, pressure…).

   

  After connecting the device to a PC with Pico Technology’s Picolog 6 measurement program installed, the voltage [V] can be processed using math channels and directly recorded in real time as temperature, current, resistance, frequency, % and pressure, see measurement example at the end of the document.

   

  For temperature measurement, the device is compatible with resistance thermometers (Ni 1000, Ni 5000, Pt 1000. Power is provided via USB-B, the maximum electrical consumption of the device is 500 mA.

   

  Device Usage

  • Temperature measurement with different temperature sensor (resistance thermometers Ni 1000, ni 5000, Pt 1000)
  • Voltage measurement
  • Conductivity and resistance measurement
  • Amperometry measurement

  SPE Connector.GC.1 for measurements in glass

  The connector enables the use of the biosensor or electrochemical sensor based on the substrates AC1, AC4 and TS1 in glass cell TC4, TC5, TC6 or TC7.

   

  The connector enables measurement with screen printed electrodes with width 7.26 mm and standard contact pads pitch (2.54 mm).
  It is compatible with other SPE´s that use the same distance between the contact pads (2.54 mm). The cone at the connector sensor side is NJ 8/10 which enables to use the connector with any standard chemical vessels.

  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).

  Basic Sample Holder – metal contact, 4 mm max. thickness (redox.me)

  Basic Sample Holder with a metal contact works as an electrical conductor between an electrode material (free-standing or deposited on a substrate) and an external circuit. This holder consists of PEEK body, pure Tantalum, Stainless Steel 316L, Titanium, Copper or Nickel metal electrical contact, and PEEK screw to fix the electrode. It is compatible with most of inorganic and organic based plates, free-standing membranes or thin films deposited on flexible and rigid substrates. A maximum thickness of the sample is 4 mm. Tantalum is known to be inert to practically all organic and inorganic compounds. Tantalum’s corrosion resistance is very similar to that of glass, as both are unsuitable for use in hydrofluoric acid and strong hot alkali applications. Therefore, in those cases, we recommend the other wire contact variant.  The metal contact can be fully immersed in the electrolyte. 

   

  Application note
  Generally, the electrode is fabricated by fixing the electrochemical active sample into the holder using a screw. Such electrode is immersed in the ion-conducting solution as a working electrode or counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. Metal wire contact is permanently installed in the PEEK body. The holder is designed to be used multiple times. The holder should be cleaned prior to the installation of electrode material.

   

  Specification
  holder body material: PEEK
  rod diameter: 6 mm
  contact material: Ta, SS 316L, Ti, Cu or Ni
  contact wire diameter: 0.6 mm
  contact wire total length: 110 mm
  holder length: 70 mm
  maximum sample thickness: 4 mm
