  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

  Silver / Silver Chloride Refillable Reference Electrode – 6 mm dia. (redox.me)

  It is a compact refillable Ag/AgCl reference electrode equipped with ceramic frit molten into the glass body. This electrode outperforms competing products in terms of mechanical stability, voltage stability and lifetime. In general, the reference electrode is composed of a system of phases, which retain an essentially constant composition, and therefore provides a stable potential by which the working electrode potential can be monitored. The phases present in reference electrodes undergo reversible redox processes at a very high rate, enabling them to rapidly adjust to changes in the solution’s ionic activity, but leaving them sensitive to the passage of large current densities. 

   

  Application note
  This electrode is commonly used with aqueous acidic electrolytes, but due to the low resistance of the frit it can be used with standard non-aqueous electrolytes, as well. The reference electrode should be stored with the rubber plug applied on the tip. Please see the full instruction here. Keeping in the solution may shorten its lifetime (the electrode operates well as long as there is at least ¼ of the solution in the electrode tube). Before use rinse it with deionized water. If air bubbles are present around the porous frit, flick the tip several times to remove them. For cleaning use detergent (dish washing detergent with water), alcohols or acetone and rinse it with deionized water at the end. To re-fill the electrode please follow this article. 

   

  Specification
  effective length: 30 mm or 70 mm
  tube diameter: 6 mm
  filling solution: 3M KCl
  potential stability: <5 mV
  frit resistance: 2-10 kohm at RT
  operating temperature: 0-100 deg C
  potential vs SHE at 25 °C: 0.207 V

  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
