Glassy Carbon Electrode Clamp

Overview

The Glassy Carbon Electrode Clamp is a precision-engineered holder designed to securely mount glassy carbon electrodes for high-performance electrochemical measurements. Glassy carbon is widely used as a working electrode material due to its chemical inertness, wide potential window, low background current, and excellent electrical conductivity. This clamp ensures stable electrical contact while maintaining mechanical integrity during experiments.

Principle of Operation

The clamp functions by firmly gripping a glassy carbon rod or disc electrode while providing a reliable electrical pathway to the potentiostat. The conductive contact (typically stainless steel or gold-plated metal) minimises contact resistance, enabling accurate current and potential control during electrochemical testing.

Key Features and Specifications
