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 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.Compared with other reference electrodes, Ag/AgCl reference electrode is more sensitive to light. Therefore, when not in use for a short period of time, it is necessary to remove the rubber cap at the lower end of the Ag/AgCl reference electrode and soak it in a dark cup filled with saturated potassium chloride solution for storage. When it is not used for a long time, it is necessary to add a new filling solution to the Ag/AgCl reference electrode, cover it with a rubber cap, and store it away from light.

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 size of Reference Electrode?

 How to choose the size of Reference Electrode? The diameter of   ERA131B [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ4*50mm Glass Rod ]   glass tube is 4mm, which is not the best choice for CHR221B2. The diameter of   ERA131A [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ6*70mm Glass Rod ] is 6mm, which is more suitable for CHR221B2.     L et me   briefly introduce this electrochemical cell for you.I attached two images, so you can see it clearly: Figure 1   is the default opening diagram of   CHR221B2 [ H-Type Sealed Electrochemical Cell 30ml 45ml ] .   The left side is the working electrode chamber opening diagram, and the right side is the counter electrode chamber opening diagram. As shown in the parameter diagram on our product details page, we place the working electrode and the reference electrode in a chamber, and are equipped with gas inlet and outlet holes [for inert gas protection and oxygen-free o...

In Situ Raman Electrochemical Cell

In Situ Raman Electrochemical Cell is a specialized setup used in Raman spectroscopy to study chemical reactions and processes that occur at electrode surfaces under electrochemical conditions. Raman spectroscopy is a technique used to analyze the vibrational modes of molecules, providing information about molecular structure, composition, and interactions.   In an in situ Raman electrochemical cell, the setup integrates a Raman spectrometer with an electrochemical cell, allowing researchers to monitor changes in molecular composition and structure in real-time as electrochemical reactions take place at the electrode surface. This setup enables detailed insights into the mechanisms of electrochemical reactions, the formation of reaction intermediates, and the behavior of catalysts or electrode materials under working conditions. Key components of an in situ Raman electrochemical cell typically include: Electrochemical cell: This includes electrodes (working electrode, reference ele...
