Product Description
Graphite Rod
High-Purity Conductive Graphite | Electrochemical & Laboratory Grade
Product Overview
FrankLab Graphite Rods are manufactured from high-purity, dense graphite with excellent electrical conductivity, chemical stability, and thermal resistance. They are widely used as counter electrodes, current collectors, heating elements, and structural components in electrochemical, energy, and high-temperature laboratory applications.
Thanks to their low cost, high durability, and inert behavior in most electrolytes, graphite rods are an ideal alternative to noble-metal electrodes for long-term experiments and scale-up studies.
Key Features
•High Purity Graphite Excellent chemical inertness and electrochemical stability
•Good Electrical Conductivity Suitable for constant current and long-duration electrolysis
•High Temperature Resistance Stable performance under elevated temperatures
•Easy Machining & Customization Can be cut, drilled, or machined upon request
•Cost-Effective Counter Electrode Solution Ideal replacement for platinum in many applications
Typical Applications
•Electrochemical counter electrodes (CE)
•Water electrolysis & electrocatalysis testing
•Fuel cell & flow battery research
•Corrosion and electroplating experiments
•High-temperature heating elements
•Laboratory reactors and custom fixtures
•Educational and industrial R&D setups

Typical Use as Counter Electrode (CE)
Graphite rods are commonly used as counter electrodes in:
•CV / LSV / EIS measurements
•Constant-current electrolysis
•Long-term stability tests
Note: Graphite may undergo slow oxidation under very high anodic potentials. For highly oxidative environments, platinum or titanium-based electrodes may be recommended.
