Glassy (Vitreous) Carbon Substrate - Small Sizes
Price: On Request
Description
A pure carbon material (>99.9%) with a fullerene-related structure, commonly used as a working electrode or current collector in electrochemical measurements. Available in five lateral sizes (5x5, 7x7, 10x10, 15x15, 20x20 mm) and four thicknesses (0.3, 0.5, 1, 2 mm). Extreme corrosion resistance in acidic and alkaline media; does not form intercalation compounds.
Application note
Typically a thin film of the studied material is deposited on the glassy carbon surface. Special attention should be paid to adhesion between the studied material and substrate. Surface pretreatment such as polishing, vacuum heat treatment, laser activation, or electrochemical activation may be applied to improve adhesion. After use, the substrate can be chemically cleaned and mechanically polished with micro-sized abrasives followed by sonication. The substrate can be used repeatedly.
