RRDE Glassy Carbon Rotating Ring-Disk Electrode

Product Introduction
The RRDE Glassy Carbon Rotating Ring-Disk Electrode is a specialized working electrode designed for electrochemical experiments involving reaction mechanisms, catalytic activity, and mass transport. Its rotating ring-disk configuration combines a central disk electrode with a surrounding ring electrode, allowing researchers to investigate electrochemical reactions at the disk and detect reaction intermediates or products at the ring.
The electrode features an insulating shroud made from PTFE (Teflon) or PEEK, a conductive disk core, and a threaded tip interface for ring-electrode contact. Available electrode materials include glassy carbon, platinum, and gold, supporting a wide range of electrochemical research applications. Standard disk diameters include 3 mm, 4 mm, and 5 mm, with customized dimensions available on request.

Performance Features
1. Insulating Electrode Shroud
The electrode tip is enclosed in an insulating shroud made from PTFE or PEEK to electrically isolate the working electrode surfaces from the surrounding environment. PEEK is specified for use below 100°C.
2. Secure Ring Electrode Connection
The threaded tip interface provides electrical contact with the ring electrode, supporting reliable assembly of the ring-disk configuration.
3. Conductive Disk Core
The disk core establishes electrical contact with the disk electrode surface, enabling the disk to function as an independent electrochemical reaction site.
4. Multiple Electrode Materials
Available ring-disk electrode materials include glassy carbon, platinum, and gold, allowing researchers to select suitable surfaces for different reaction systems and experimental objectives.
5. Multiple Disk Diameters
Standard disk inner diameters are available in 3 mm, 4 mm, and 5 mm options to accommodate different experimental requirements.
6. Customizable Dimensions
Custom dimensions can be supplied on request to meet specific electrochemical cell configurations and research needs.

Working Principle
A rotating ring-disk electrode (RRDE) consists of a central disk electrode surrounded by a concentric ring electrode, separated by an insulating gap. During an experiment, the electrode rotates at a controlled speed in an electrolyte, generating a defined hydrodynamic flow near the electrode surface.
Electrochemical reactions occur at the disk when an appropriate potential is applied. Reaction intermediates or products generated at the disk can be transported by the flowing electrolyte to the surrounding ring, where they may be detected through a separately controlled potential.
This configuration enables researchers to investigate reaction pathways, evaluate catalyst selectivity, study intermediate formation, and analyze mass transport effects. The combination of a glassy carbon disk and a suitable ring material provides a versatile platform for electrochemical catalyst and fuel cell research.

Frequently Asked Questions
1. What is an RRDE glassy carbon electrode used for?
It is used in electrochemical research to investigate reaction mechanisms, catalyst performance, corrosion behavior, and mass transport, particularly when products or intermediates from a disk reaction need to be detected at the ring.
2. What is the difference between an RRDE and an RDE?
An RRDE combines a central disk and a surrounding ring, enabling complementary electrochemical measurements. An RDE has a single rotating disk and is primarily used to study reactions occurring at that surface.
3. What disk diameters are available?
Standard disk diameters are 3 mm, 4 mm, and 5 mm. Custom dimensions can be requested.
4. Which electrode materials are available?
Available configurations include platinum, gold, and glassy carbon. Material selection depends on the reaction being investigated and the required electrode properties.
5. What materials are used for the insulating shroud?
The insulating shroud is typically made from PTFE (Teflon) or PEEK. The supplied specification states that PEEK can be used below 100°C.
6. How does the ring electrode detect reaction intermediates?
The disk generates reaction products or intermediates, which may be transported to the ring by the rotating electrolyte flow. Applying a suitable potential to the ring allows electroactive species to be detected.
7. Can the electrode dimensions be customized?
Yes. Customized dimensions are available on request. Confirm the required disk diameter, ring geometry, shaft dimensions, and compatibility with the rotating electrode assembly when ordering.
8. Is the RRDE suitable for fuel cell catalyst research?
Yes. RRDE systems are widely used to study fuel cell electrocatalysts, particularly for evaluating oxygen reduction reaction activity and selectivity and estimating peroxide-related reaction pathways.
