Custom Platinum Electrodes
Introduction
- Designed for high-precision electrochemical research, our high-purity platinum electrode clamp ensures a reliable, contamination-free electrical connection for your test samples. The contact portion is crafted from ≥99.99% pure platinum, which effectively eliminates side reactions and secondary catalytic effects that occur with standard stainless steel or copper clips. This makes it an indispensable tool for sensitive experiments such as Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and corrosion studies in aggressive acidic or alkaline electrolytes. By providing a stable and low-resistance interface, this clamp guarantees the integrity of your data and the reproducibility of your research results.

Fully Customizable Design for Versatile Lab Applications We understand that electrochemical cells come in various sizes and configurations, which is why our platinum clamps are fully customizable. The standard body is made of high-grade PTFE (Teflon) or PEEK, providing excellent insulation and resistance to most organic solvents and corrosive chemicals. You can customize the rod length, diameter, and the jaw opening width to accommodate different sample thicknesses, from ultra-thin foils to multi-layered membranes. Whether you are testing fuel cell catalysts, battery electrodes, or bio-sensors, our engineering team can tailor the connector type and clamping mechanism to integrate seamlessly with your existing potentiostat and glassware setup.
