L- Shape Gold Disk Electrode

L-Shape Gold Disk Electrode (Au) — PTFE Insulated

High-Purity Gold · 0.5–6 mm Disk Diameter · Custom Geometry

The FrankLab L-Shape Gold Disk Electrode is a precision-engineered working electrode designed for experiments requiring a vertical immersion section combined with a horizontal sampling surface.
This structure prevents cable interference, reduces vibration influence, and offers excellent flexibility when used in small-volume electrochemical cells, in-situ spectroscopy setups, or confined reaction chambers.

Manufactured using ≥99.99% high-purity gold, the electrode provides outstanding chemical stability, a clean electrochemical interface, and exceptional reproducibility for surface chemistry and catalytic studies.

Key Features

• High-Purity Gold (≥99.99%)

Ensures exceptionally clean electrochemical behavior, enabling highly sensitive surface studies.

• Right-Angle ‘L’ Configuration

• Facilitates immersion depth control

• Convenient for micro-cells and tight reaction spaces

• Prevents cables from contacting the electrolyte

• Mirror-Polished Gold Disk

Provides ultra-low background current and excellent reproducibility for voltammetric techniques.

• PTFE Insulation

Fully inert to most acids, bases, and solvents; easy to clean and long-lasting.

• Customizable Design

Full control over disk diameter, L-arm length, insulation diameter, and wire type.

Applications

• Self-assembled monolayers (SAMs) on gold

• Thiol–gold surface chemistry

• Biosensor and chemical sensor development

• Electrocatalysis benchmarking (ORR, CO₂RR, organic electrochemistry)

• Cyclic voltammetry (CV), LSV, DPV, EIS

• Surface kinetics and electron-transfer studies

Benefits of L-Shape Design

✔ Prevents electrolyte from wicking up the cable
✔ Provides stable horizontal measurement geometry
✔ Ideal for in-situ optical and spectroscopic setups
✔ More ergonomic positioning inside multi-electrode cells
