Custom Gold Sheet Electrodes
مقدمة
- Our high-purity gold disc electrodes are manufactured from ≥99.99% Au, providing excellent electrical conductivity, biocompatibility, and corrosion resistance for demanding electrochemical applications. Each disc is precision-machined with tight tolerances on diameter and thickness, ensuring a well-defined active area and uniform current distribution. This makes them ideal as working electrodes for cyclic voltammetry, EIS, amperometry, biosensors, microfluidic systems, and medical or neural interfaces, where low background noise and stable potential are critical for accurate, reproducible measurements.
-
We offer fully customizable gold round electrodes tailored to your specific setup. Diameters, thicknesses, and edge designs (flat or chamfered) can be produced according to your drawings, and we support options such as mirror-polished, roughened, micro-structured, or chemically activated surfaces to optimize sensitivity and reaction kinetics. Tabs or lead wires can be welded for easy integration into holders and OEM devices. Available from small R&D quantities to batch production, our custom Au disc electrodes are a premium choice for universities, research institutes, sensor manufacturers, and medical device developers looking for stable, ready-to-use electrochemical components.
