Coiled Platinum electrodes are available in two sizes and are compatible with all electrochemical cell systems.

Platinum plate electrodes can usually be used as auxiliary/counter electrodes for various electrochemical measurements in three-electrode cell-system. Platinum is the first choice for counter electrode for many electrochemical applications due to its inertness and stability in different electrolyte. Compared to mesh and wire-type, platinum plate electrode has higher surface area to match and support the current generated on the working electrode in any chemical reactions. Due to platinum plate electrode’s resistance to oxidation, it is an excellent choice for anode in several electrochemical processes, such as the electrolysis of an acetate salt to give ethane and carbon dioxide. It is also used in several industrial application like cathodic protection and electroplating. Their stability in harsh environment provides accurate results.

Metal Bipolar-plate MEA Electrolytic Cell (Titanium) Built around high-purity metal plates (typically titanium), this MEA cell emphasizes electrical/thermal conductivity and mechanical strength for sustained operation at elevated current densities. Standard active areas include 10×10, 20×20, 30×30, and 50×50 mm with serpentine or parallel channels; gold-plated copper collectors are available in selected configurations to reduce contact resistance. Hardware options include double O-ring sealing and ports for temperature monitoring or heating, enabling tightly controlled test conditions for alkaline AEM electrolysis, PEM studies, and CO2RR. The modular architecture supports swapping channel plates or materials (e.g., nickel variants for specific chemistries) to align with durability and corrosion-resistance goals. This platform is ideal for researchers comparing catalyst layer performance across load cycles or optimizing water/gas management under practical current densities.

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.
