Electrode Polishing Kit

Product Description

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.

FAQs

1. Which alumina grade should I finish with?
Most labs finish at 0.05 µm after stepping through 1.0 and 0.3 µm as needed; this yields a smooth, reproducible surface for voltammetry.

2. How do I avoid cross-contamination between grits?
Use separate pads for each alumina grade, rinse the electrode thoroughly between steps, and refresh pads regularly.

3. Can I start with abrasive paper?
For stubborn films or significant scratches, a very fine abrasive (e.g., 1200–2000/3000#) may be used before moving to alumina slurries, then finish at 0.05 µm.

4. Which electrodes are compatible?
Disk-type glassy carbon, gold, and platinum electrodes (including RDE/RRDE tips) are routinely polished with these materials following manufacturer guidance.
