Platinum Ring Electrode

Product Overview

The FrankLab Platinum Ring Electrode is fabricated from high-purity platinum wire (>99.99%), formed into a precise circular ring and mounted inside a chemically resistant PTFE or PEEK body with a gold-plated copper terminal.

Compared with standard Pt disk or rod electrodes, a Pt ring electrode offers:

• Uniform radial current distribution

• Reduced ohmic drop

• High mass-transfer sensitivity

• Improved signal-to-noise ratio in analytical experiments

These advantages make Pt ring electrodes ideal for:

• Hydrodynamic systems

• Mechanistic electrochemistry

• RRDE (rotating ring) related measurements

• Electrocatalyst screening

• Dissolved oxygen / peroxide detection

• Electrochemical kinetic studies
