Carbon Paste Electrode
Carbon Paste Electrode (CPE) used as a working electrode in electrochemical experiments. It typically consists of a PTFE or Teflon cylindrical body with a metal (brass or copper) rod used to compress and connect the carbon paste.
Read Full Description +Key Characteristics
- Refillable carbon paste cavity at the electrode tip
- PTFE/Teflon insulating body
- Metal pushing rod (brass/copper) for electrical connection
- Available diameters: usually 2 mm, 3 mm, 4 mm, or 5 mm
- Renewable surface by replacing or polishing the carbon paste
Common Applications
- Cyclic Voltammetry (CV)
- Electrochemical sensors and biosensors
- Environmental and pharmaceutical analysis
- Electrochemical research and teaching labs
Carbon paste electrodes are widely used because their surface can be easily renewed and modified with catalysts, enzymes, or nanoparticles, making them ideal for sensor development and analytical electrochemistry.
