Platinum Mesh Electrode

Platinum Mesh Electrode for Electrochemical Research

The Platinum Mesh Electrode is a high-purity noble-metal counter electrode designed for reliable current carrying in two-electrode and three-electrode electrochemical systems. In a typical setup, the potentiostat controls the working electrode potential versus the reference electrode, while the platinum mesh completes the circuit as the counter electrode. The mesh geometry provides a larger effective surface area than a simple wire, which helps reduce counter-electrode polarisation and supports stable current flow during demanding measurements.

Working Principle and Key Features

A platinum mesh electrode is widely used where researchers need a conductive, chemically robust and reproducible auxiliary electrode. The open mesh structure improves electrolyte access and helps bubble release during gas-evolving reactions, making it useful in both analytical electrochemistry and preparative electrolysis.

Typical features include:

• High-purity platinum mesh for excellent conductivity and corrosion resistance
• PTFE-insulated body for chemical compatibility and easy handling
• Reinforced rectangular or circular mesh formats for improved mechanical stability
• Common body geometry around 6 mm diameter with an insulated shaft and rear connection pin
• Multiple mesh sizes to suit low-current and larger-area electrochemical cells
• Customisable mesh geometry, dimensions and connection style to match specific experimental requirements

Available formats commonly include rectangular meshes such as

• 5 × 10 mm
• 10 × 10 mm
• 10 × 20 mm
• 10 × 30 mm
• 15 × 15 mm
• 20 × 20 mm
• 30 × 30 mm,
• circular mesh - 10 mm diameter
• circular mesh - 10 mm diameter
  
  

Compatibility and Applications

This electrode is compatible with many standard electrochemical workstations, potentiostats, H-cells, jacketed cells, spectroelectrochemical cells and customised test assemblies. It is commonly used in:

• Cyclic voltammetry, chronoamperometry, chronopotentiometry and EIS
• Battery and supercapacitor research
• Water splitting and hydrogen evolution studies
• Fuel cell and electrocatalysis experiments
• Corrosion, sensor and plating research
  
  

Customisation Options

ScienceGears can also customise the platinum mesh electrode according to the end user’s requirements. Depending on the application, we can discuss custom mesh size, shape, exposed area, shaft length, insulation style, connector format and overall electrode geometry. This is particularly useful for researchers working with non-standard electrochemical cells, specialised reactors, scale-up studies or application-specific test setups.
