Rotating Ring Disk Electrode - RRDE External Thread (Compatible with Pine)

Rotating Ring Disk Electrode - RRDE External Thread (Compatible with Pine)

Product Overview

The Rotating Ring-Disk Electrode (RRDE) allows for simultaneous data collection from both the disk and ring electrodes, providing a comprehensive understanding of electrochemical reactions. The disk diameter is available in either 5.00 mm or 6.00 mm, and can be made from Glass Carbon (GC), Gold (AU), or Platinum (PT). This dual-electrode system is widely used in electrocatalysis, reaction mechanism studies, and product analysis.

The RRDE system is suitable for:

• Electrocatalyst evaluation and product analysis

• Lithium-air battery studies

• Oxygen reduction and oxygen evolution reactions (ORR/OER)

• Electrochemical kinetics and product analysis

The external threaded design ensures stable connection and reliable signal transmission, and the PTFE/PEEK encapsulation offers superior resistance to chemical degradation.
