Custom Gold Sheet Electrodes
Introducción
- Our high-purity gold sheet electrodes are engineered for demanding electrochemical and biosensing applications where stability, accuracy, and corrosion resistance are critical. Produced from ≥99.99% Au, these electrodes provide excellent electrical conductivity, low background noise, and outstanding chemical inertness, making them ideal for use in biosensors, medical diagnostics, microfluidic chips, electrochemical analysis, and catalytic studies. Each plate is manufactured with tight tolerances on thickness and flatness to ensure uniform current distribution and highly reproducible measurement results in a wide range of electrolytes and operating conditions.

We specialize in fully customized gold electrode sheets to match your exact technical requirements. Available from ultra-thin foils to thicker plates, our Au electrodes can be precision-cut into rectangles, discs, chips, or complex CNC‑machined geometries according to your drawings. Surface options include mirror‑polished, mechanically roughened, micro‑structured, or chemically activated finishes to optimize active area and reaction kinetics. OEM and research customers can also request tab welding, patterning, and cleanroom-grade packaging. With stable quality, flexible customization, and professional technical support, our gold sheet electrodes are an excellent choice for universities, laboratories, sensor manufacturers, and high-end device developers.
