  • 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).

  • PME011 Microdialysis Catheter Microeye

    Microdialysis catheter is provided with a special membrane which produces a “plasma-like” sample without the need for blood centrifugation.

     

    It enables “plasma-like” samples taking and continuous monitoring of low-molecular substances in circulating blood without withdrawing blood from the patient. It offers virtually real-time information. Samples can be collected for off-line analysis if required. This catheter is easy to use and reduces risks of contact with blood borne pathogens. The MicroEye is intended for intravenous use for periods up to 48 hours and is inserted via 18G blood catheter.

     

    The range of substances that can be monitored using this catheter

    • Electrolytes (such as potassium, magnesium etc.)
    • Energy metabolites (glucose, lactate, pyruvate, etc.)
    • Amino acids (glutamate, GABA, etc.)
    • Hormones and neurotransmitters (dopamine, serotonin, etc.)
    • Inflammatory mediators and growth factors (cytokines, etc.)
    • Drugs and their metabolites (unbound “free fractions and /or total

  • Activation furnance for electrochemical sensors

    The activation furnance is a device used for curing individual sensors of the AC1 type. At a defined temperature (up to 1000 °C) depending on the electrode and sensor materials. When the sensor is cured, the surface of the electrodes is cleaned from surface oxides and organic impurities, which results in regeneration of the sensor or its activation. In this way, for example, old sensors with immobilized enzyme layers can be cured for reuse – see example at the end ot the document.

  • 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

    holder length: 70 mm
    maximum sample thickness: 4 mm
