Graphite Disk Working Electrode – Ø2 to Ø5 mm

The Graphite Disk Working Electrode provides a defined circular graphite working surface mounted flush in a white insulated holder. A gold-colored contact pin allows straightforward connection in compatible electrochemical cells and laboratory test setups.

Choose from four disk diameters—Ø2 mm, Ø3 mm, Ø4 mm, or Ø5 mm—to match the geometric working area required by your method.

Key features

• Flush-mounted graphite disk working surface
• Defined circular geometry for controlled electrochemical measurements
• White insulated holder with gold-colored contact pin
• Four selectable disk diameters
• Suitable for compatible three-electrode research setups, cyclic voltammetry, method development, and electrode studies

Available disk diameters

• Ø2 mm
• Ø3 mm
• Ø4 mm
• Ø5 mm

Use and care

Clean and, when required by the method, polish the exposed graphite disk between measurements. Confirm electrolyte compatibility, potential window, cleaning procedure, and cell connection before use. Graphite is not chemically inert under every electrochemical condition.
