Glassy Carbon Electrode Straight Type PTCFE Rod

Glassy carbon electrode is one of the most widely used working electrodes, and it is a better inert electrode. Glassy carbon electrode has many advantages such as good conductivity, high hardness, high finish, high hydrogen overpotential, and wide polarization range. Its chemical properties are very stable, and it can be used as an inert electrode for direct anodic dissolution testing, and voltammetric determination of cathodes and variable valence ions. Using glassy carbon electrodes as the substrate, chemically modified electrodes can also be prepared.

There are four types of insulating rods for glassy carbon electrode jackets.

Glassy carbon electrodes are divided into straight type, L type, T type and detachable type. The straight glassy carbon electrode material faces vertically downwards, and the research material is coated on the glassy carbon material surface for testing. The reference electrode is matched with a curved luggin capillary salt bridge close to the material surface of the glassy carbon electrode, which can effectively reduce the R drop and improve the test effect.

What is the CO2RR Gas Diffusion Flow Cell?

The CO2RR Gas Diffusion Flow Cell (CO2RR GDFC) is a type of electrochemical cell used in the conversion of carbon dioxide (CO2) to other chemicals through a process called the CO2 reduction reaction (CO2RR). It is similar in design to the Gas Diffusion Flow Cell (GDFC) used to measure gas permeability, but it is specifically designed to facilitate the electrochemical reduction of CO2. The CO2RR GDFC consists of a small, sealed chamber with two compartments separated by a thin, gas-permeable membrane. One compartment is filled with a CO2-containing gas mixture, while the other compartment contains an electrolyte solution and a catalyst material, such as copper or silver, which facilitates the CO2RR. The two compartments are separated by the gas-permeable membrane, which allows CO2 to diffuse from the high concentration compartment to the low concentration compartment. The CO2RR is driven by an electric potential applied across the two compartments, which induces the reduction of CO2 int...

How to Choose the Reference Electrode?

According to the test requirements, you can use the following content as a reference for selecting reference electrode. Different research systems can choose different reference electrodes: Neutral system: saturated calomel electrode or Ag/AgCl reference electrode Alkaline system: Hg/HgO reference electrode Acidic system: Hg/Hg2SO4 reference electrode Non-aqueous system: Non aqueous Ag+ reference electrode Compared with other reference electrodes, Ag/AgCl reference electrode is more sensitive to light.At the same time, the silver chloride electrode is also less affected by temperature than other types of reference electrode. If you choose calomel electrode, Hg2/HgSO4 electrode or Hg/HgO electrode, you can add a salt bridge under the electrode to protect the reference electrode and minimize the potential affected by temperature. Mercury Oxide Reference Electrode Hg/HgO PTFE Rod 6 * 60 mm is a good choice for the Alkaline system. you can find all the reference electrodes from ...

Ag AgCl Reference Electrode Silver Silver Chloride Φ6*140mm Glass Rod

In electrochemistry, in order for a specific reaction to occur, a stable electric potential needs to be applied to the working electrode. The potential of the working electrode should always be accurately controlled. This is why a reference electrode is needed as a potential reference standard. Common reference electrodes include Silver Silver Chloride Ag/AgCl reference electrode, saturated calomel electrode,Hg/HgO reference electrode, Hg/Hg2SO4 reference electrode and Non aqueous Ag+ reference electrode,etc. The silver-silver chloride (Ag/AgCl) electrode is the most commonly used reference electrode. Compared with calomel electrodes that use mercury and its salts, Ag/AgCl electrodes are more environmentally friendly. Its electrode potential also has sufficient stability, reliability and reproducibility. Special attention should be paid to maintenance and storage when using Ag/AgCl reference electrode. Before use rinse it with deionized water. If air bubbles are present around the poro...
