A full set Electrode Polishing Kit This complete Electrode Polishing Kit streamlines surface renewal for disk-type working electrodes, helping you recover clean, reproducible electrochemical responses prior to CV, LSV, DPV and EIS. The set includes two 100 × 100 mm glass bases for flat, stable polishing; three alumina grades (1.0 µm, 0.3 µm and 0.05 µm, 20 g each) to execute a reliable coarse-to-fine sequence; five velvet and five microcloth pads to match abrasive step and finish; plus five 2000# and five 3000# abrasive papers for initial corrective work on stubborn films or scratches. Following an industry-standard workflow, users typically begin (only when needed) with very fine paper, then step through 1.0 µm → 0.3 µm → 0.05 µm alumina, rinsing well and using separate pads at every stage to avoid cross-contamination. This approach is widely recommended to maintain planarity and achieve mirror-like finishes on glassy carbon, platinum and gold electrodes, supporting consistent electron-transfer kinetics and low background currents. Applications span electrocatalysis (HER/OER, CO2RR), corrosion studies, battery and fuel-cell R&D, and electrochemical sensing—any workflow where surface state drives kinetics and data quality. The kit pairs well with standard disk electrodes (including RDE/RRDE tips) from leading suppliers and fits seamlessly into routine lab maintenance.
