Glassy Carbon–Platinum Rotating Ring-Disk Electrode (GC–Pt RRDE)

Overview

The Glassy Carbon–Platinum Rotating Ring-Disk Electrode (GC–Pt RRDE) from ScienceGears enables advanced electrochemical analysis where simultaneous detection of intermediate species or reaction products is required. Featuring a glassy carbon disk surrounded by a platinum ring, this configuration allows independent control of the disk and ring potentials, providing real-time insight into multi-step electrochemical mechanisms.

Principle of Operation

In RRDE systems, the disk electrode initiates a redox reaction, while the ring electrode detects reaction intermediates or by-products transported through the rotating diffusion layer. The GC–Pt combination offers a chemically inert surface for reaction initiation (GC) and a catalytically active ring for detection (Pt), making it ideal for oxygen reduction, fuel cell, and redox mediator studies.

Key Specifications

• Disk Material: High-purity glassy carbon (5 mm standard)
• Ring Material: Platinum, precisely aligned around the GC disk
• Body Material: Chemically resistant PTFE or PEEK housing
• Electrical Contacts: Dual independent gold-plated connectors
• Typical Collection Efficiency: ~37% (customisable upon request)
• Compatibility: Fits RRDE rotators from Autolab, Ivium, Pine, ALS Japan, BioLogic, and Gamry
  
  

Applications

Ideal for:

• Oxygen reduction and peroxide detection (ORR/H₂O₂ studies)
• Fuel cell catalyst characterisation
• Redox mediator and electron transfer kinetics
• Electrocatalyst screening and mechanistic analysis
