Graphite Rod Electrode, >99.99%Purity

Product Description
Shipping & Delivery
Graphite Rod Electrode | High-Purity Carbon Material | FrankLab

Product Overview
The FrankLab Graphite Rod Electrode is a high-purity carbon electrode designed for a wide range of electrochemical applications. Graphite rods provide excellent electrical conductivity, a wide potential window, and strong chemical resistance in acidic and neutral environments—making them one of the most versatile and economical working electrodes for laboratory research.
This electrode is suitable for:
Cyclic Voltammetry (CV)
Linear Sweep Voltammetry (LSV)
Electrochemical Impedance Spectroscopy (EIS)
Electrosynthesis & electro-oxidation
Corrosion studies
Battery and capacitor research
General electrolytic operations
FrankLab offers both standard bare graphite rods and fully customized sizes to meet diverse research needs.

Key Features
• High-Purity Graphite Material
Stable electrochemical behavior
Excellent electrical conductivity
Smooth surface for reproducible results
Wide potential window in aqueous systems

• Excellent Chemical Resistance
Highly resistant in acidic and neutral electrolytes
