  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.

  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

  SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)

  The SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.

   

  The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
  The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H₂O₂ which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.

   

  * For this product, we recommend our customers use the Training Service from BVT.

  TS Testing Sensor

  Simple identifier of electrochemical hardware error

  Dimensions: 25.4 x 7.26 x 0.63 mm

   

  Electrochemical measurements are very sensitive. Sometimes cables, connectors and their wetness can create the measurement errors. Testing sensor enables simple identification of electrochemical hardware error. The sensor has same geometry as AC1 type but its response produced by resistor. The response is stable and independent on chemistry. Testing sensor is formed on a corundum ceramic base. At the end of the sensor there is a contacting field which is connected with the SMD resistors by the silver conducting paths which are covered by a dielectric protection layer.

  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.

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.
