Platinum Disk Electrode/Pt Disk, >99.99% Purity,
Platinum Disk Electrode (Pt) — High-Purity,
The FrankLab Platinum Disk Electrode is designed for high-accuracy electrochemical measurements where stability, corrosion resistance, and long-term durability are essential. Using ≥99.99% purity platinum and precision polishing technology, each electrode delivers exceptionally low background current and highly reproducible electrochemical responses.
Ideal for applications including HER/OER, oxygen evolution studies, reference kinetics benchmarking, catalyst evaluation, and fundamental electron-transfer mechanism research.
