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.

Metal Wire Auxiliary Electrode – 50HX15 0.6/250 mm (redox.me)
Read moreThe metal wire counter (auxiliary) electrode is provided in the electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.
Application note
The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package).Specification

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

The sensor is made on a corundum ceramic base. Working, reference and auxiliary electrodes are applied to this surface. Working, reference and auxiliary electrodes are made of different materials. At the end of the sensor there is a contact field that is connected to the active part by silver conductive paths that are covered with a dielectric protective layer. The working electrode of the sensor with a diameter of 2 mm is made of a material of guaranteed purity of up to 99.99 % depending on the selected material– standard layer thickness 0.0125 mm.
We also offer a working electrode made of polished gold AC1P.W*.R*, with homogenous surface with roughness less than 1 µm.
We also offer activated graphite sensors on customer request.
