Platinum Electrode Clamp / Holder

Precision electrode holding for reliable electrochemistry

The Platinum Electrode Clamp is a research-grade holder designed to provide a stable electrical connection between a potentiostat lead and a conductive sample used as the working electrode. In a typical three-electrode configuration, the clamp secures the sample mechanically while the conductive platinum contact transfers current efficiently to the electrode. The insulating outer body helps isolate the electrical connection from the electrolyte, supporting reliable and reproducible electrochemical measurements in laboratory environments. Comparable holder designs are widely used in electrochemistry, battery testing, fuel cell research, electrolyser studies, and photoelectrochemical experiments.

Principle of operation and design

This style of electrode clamp is particularly useful when the researcher needs to hold sheets, foils, meshes, rods, wires, coated substrates, conductive glass, or other flat and shaped conductive materials as the working electrode. Commercially available comparable designs commonly use a platinum sheet or platinum contact element together with an insulating PTFE or PEEK body. Standard rod-style formats in the market are often around 6 mm in diameter and 60 mm in length, while plate-style holder versions are also available in formats such as 10 × 15 mm, 10 × 15 mm and 5 × 5 mm for electrochemical and photoelectrochemical studies.
