Glassy Carbon Sheet

Product Description
Shipping & Delivery
FrankLab Glassy Carbon Sheet 
• Ultra-Pure · Gas-Tight · Highly Corrosion-Resistant · Ideal for Scientific & Industrial Applications

Product Overview
Glassy Carbon, is one of the world’s highest-grade carbon materials. It combines:
• the chemical inertness of ceramic materials
• the electrical conductivity of graphite
• a pore-free, gas-tight microstructure unique to glassy carbon
These sheets are widely used as inert substrates in:
• Electrochemical research
• Semiconductor and vacuum technology
• High-temperature applications
• Corrosion testing
• Analytical instruments
• Thin-film deposition
• Sample holders and precision components
FrankLab provides sheets in all standard sizes and supports custom machining.

Key Advantages of Glassy Carbon
• Certified purity
• Traceability
• Consistent material properties
• Reliability for scientific and industrial applications
• Ultra-High Purity (<100 ppm ash)
Ensures low contamination and stable electrochemical background.
• Completely Gas-Tight
No open porosity → no absorption of electrolytes, gases, or solvents.
• Exceptional Chemical Resistance
Stable in:
• Strong acids
• Organic solvents
• Corrosive electrolytes
• High-purity water
• Extreme Temperature Resistance
• Up to 1000°C in air
• Up to 3000°C in inert gas
• High Mechanical Strength & Hardness
Suitable for precision machining, cutting, drilling, and polishing.
