Platinum Rotating Disk Electrode (Pt RDE)

Overview

The Platinum Rotating Disk Electrode (Pt RDE) from ScienceGears is a precision-engineered tool for high-accuracy electrochemical investigations requiring stable catalytic performance and reproducible surface characteristics. The polished platinum disk provides exceptional conductivity, durability, and corrosion resistance, making it the preferred choice for fuel cell, oxygen evolution (OER), and hydrogen evolution (HER) studies.

Principle of Operation

The RDE operates by rotating the electrode at a controlled rate to generate a uniform diffusion layer, allowing researchers to separate kinetic and mass-transport effects during electrochemical reactions. The platinum surface offers superior catalytic activity toward hydrogen, oxygen, and redox mediators, ensuring reliable results across diverse electrolyte systems.
