Rotating Disk Electrode/RDE, Glassy Carbon / Platinum / Gold Disk, Female Thread / Metrohm-Compatible)

Rotating Disk Electrode (RDE)

Glassy Carbon / Platinum / Gold Disk

(Female Thread / Metrohm-Compatible)

The FrankLab Metrohm-Compatible Rotating Disk Electrode (RDE) is engineered for high-precision hydrodynamic electrochemical testing, offering exceptional stability, reproducibility, and compatibility with Metrohm rotator systems.
With interchangeable disk materials—including Glassy Carbon (GC), Platinum (Pt), and Gold (Au)—this RDE supports a wide range of catalytic, mechanistic, and kinetic studies.

Available Disk Materials

1. Glassy Carbon Disk (GC)

• Disk Diameter: Ø5 mm

• Ideal for ORR, CV/LSV, catalyst benchmarking

• Chemically inert, low background current

2. Platinum Disk (Pt)

• Disk Diameter: Ø5 mm

• Suitable for acidic/alkaline media, high-temperature environments

• Best for HER/OER, redox chemistry, electrosynthesis

3. Gold Disk (Au)

• Disk Diameter: Ø5 mm

• Excellent for SAMs, thiol chemistry, noble-metal catalysis

• Ideal for surface-sensitive electrochemistry

Technical Specifications

Key Features

• Precision-Machined Disk Assembly

Each disk is embedded with micron-level tolerance to ensure stable hydrodynamic behavior and minimal vibration during rotation.

•Chemical and Thermal Stability

• PEEK body (optional): Wide temperature range (up to 80°C), excellent rigidity

• Perfect Compatibility with Metrohm Systems

• Fully matches Metrohm’s internal thread

• No adapter required

• Ensures stable rotation, low wobble, and reproducible Levich/K–L curves

• Replaceable Disk Options

Easily switch between GC, Pt, and Au to match experimental needs.
