Product Overview

The electrode uses an imported glassy carbon core, a chemically stable PTFE insulating rod and a copper-pin connection. The working face is mirror-polished for cyclic voltammetry, differential pulse voltammetry, impedance and other electrochemical tests.

Stable electrochemical window

Low adsorption and low background current for aqueous and various organic electrolytes.

Reliable construction

The glassy carbon core is coaxially fixed in the PTFE rod; the copper pin is 15 mm long and 2 mm in diameter.

Flexible customization

The standard PTFE length is 70 mm; diameter, length and geometry can be customized.

This page lists specifications only. Prices are not shown. Please confirm the selected diameter, shape and customization requirements when ordering。

Polishing & Maintenance

Wet polishing: Use nylon cloth for polishing processes requiring water lubrication.
Dry polishing (recommended): Use suede or polishing velvet with 0.05 μm polishing powder for a better mirror finish.
Level the surface with 0.3–0.5 μm powder, then finish with 0.05 μm powder. Move the electrode evenly in a figure-eight pattern.
Avoid ultrasonic cleaning whenever possible. If test data is abnormal, repolish the electrode before retesting.
For ferri/ferrocyanide tests, a peak separation ΔEp below 100 mV is generally normal. Above 100 mV, repolish first, then check the connections and solution.

Applications

Cyclic voltammetry (CV)

For redox mechanisms, reversibility and electrode kinetics studies.

Sensing & analysis

For ferri/ferrocyanide probes, environmental contaminants and biomolecule detection.

Materials & batteries

For evaluating catalysts, conductive materials, electrolytes and interfacial behavior.

Usage Instructions

Installation: Secure the electrode in a holder and fully immerse the glassy carbon face in the working solution.
Connection: Connect the glassy carbon electrode to the working-electrode terminal; connect the counter and reference electrodes according to the instrument labels.
Pretreatment: Before first use or when data drift occurs, polish the face sequentially with 0.3–0.5 μm and 0.05 μm powders.
Testing: Keep the face level, allow the solution to stand, secure all connections, and run blank and standard-system tests.

FAQ FAQ

Why is the peak separation above 100 mV?

Common causes include a contaminated or scratched face, or a poor connection. Repolish in a figure-eight pattern and check the reference electrode, salt bridge and solution.

Can ultrasonic cleaning be used?

Not recommended. Ultrasonic treatment may cause microscopic damage or loosen the connection. Gently rinse with solvent and repolish instead.

When should 0.05 μm polishing powder be used?

Use it after leveling with 0.3–0.5 μm powder to obtain a mirror-like face and better repeatability.

Can sizes be customized?

Yes. The glassy carbon diameter, PTFE length and outer diameter, and straight/L-shaped structures can be customized. Avoid excessively thin PTFE walls for service life.

Is potential correction required?

No correction is normally required with the standard structure and reference system. Verify according to your laboratory method when changing the reference electrode or solution system.

Are polishing accessories included?

Polishing powder, glass plates, velvet and suede are optional accessories and can be selected separately.
