Detachable Glassy Carbon Electrode Straight Type PTFE Rod

The working electrode refers to an electrode that can cause significant changes in the concentration of the component to be tested in the test solution during the test. Common working electrodes include disk electrodes and replaceable electrode holders. Disk electrodes include glassy carbon electrodes,platinum disk electrodes,gold disk electrodes,silver disk electrodes,graphite electrodes,etc. Replaceable electrode holders include PTFE electrode holders, PEEK electrode holders, metal electrode holders, glassy carbon electrode holders, sample holders, etc.

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 detachable glassy carbon electrode is connected by a 7mm long electrode tip and electrode rod through a thread. A separate electrode tip can be used for scanning electron microscopy and other tests.

What is the Gas Diffusion Layer (GDL)?

The GDL is a porous structure made by weaving carbon fibers into a carbon cloth (e.g. GDL-CT and ELAT) or by pressing carbon fibers together into a carbon paper. Many of the standard GDLs that are produced today come with a Micro Porous layer (MPL) and hydrophobic treatment (PTFE). The MPL and PTFE help with the contact to the membrane and with water management. The MPL typically provides a smooth layer with plenty of surface area for catalyst and good contact with the membrane. The MPL often uses PTFE as a binder that increases hydrophobicity, which helps keep the water within the membrane from escaping – drying out the membrane and causing higher resistance (lower performance). There is often an additional PTFE coating on the MPL surface to further augment this. What Exactly Does a Gas Diffusion Layer (GDL) Do? GDL essentially acts as an electrode that facilitates diffusion of reactants across the catalyst layered membrane. The surface area and porosity of the GDL is what

Platinum Wire Ring Counter Electrode Φ0.5*230mm

Platinum is an inert metal and does not participate in the electrode reaction itself, so it is the first choice for the counter electrode. One of the important parameters of the counter electrode is its surface area. The counter electrode must have a large enough area to support the current conduction generated on the working electrode. Platinum electrodes include platinum sheet electrodes, platinum wire electrodes, and platinum mesh electrodes. The platinum wire electrode has a relatively small area ，which is suitable for use in combination with a disc-shaped working electrode. The platinum wire electrode has a variety of shapes and structures, which can be bent according to the length of the platinum wire to be used with various types of electrochemical cells. The insulating rod material of the platinum wire electrode can be PTFE or PEEK rod. As the working electrode undergoes an oxidation or reduction reaction, a gas evolution reaction or a reverse reaction of the working electrode

How to do when the mercury oxide reference electrode broken?

Q: How to do when the mercury oxide reference electrode broken? A: If the electrode is broken, please be sure to operate in accordance with the laboratory hazardous chemical treatment method to avoid the diffusion of mercury oxide, which is a toxic material. Description of the mercury oxide reference electrode: The mercury-mercury oxide（Hg/HgO） reference electrode is mainly used in alkaline solutions. It is an electrode composed of metallic mercury and its insoluble salt HgO and 1M KOH solution. Its electrode potential is 0.098V (25°C). The salt bridge of the Hg/HgO reference electrode is made of glass and PTFE, and the size is φ6*70mm. This size can be matched with various types of Dek Research electrochemical cells. Special attention should be paid to maintenance and storage when using the Hg/HgO reference electrode. The substance containing mercury oxide is a toxic substance, and the salt bridge solution is corrosive. Please strictly abide by the relevant laboratory safety regulati
