About this item Electrochemical Applications: commonly used in electrochemical experimental tests and measurements, including CO₂RR, NRR, and other electrochemical reactions Replaceable Ion Membrane Design: the ion exchange membrane (NOT included) between the two chambers can be easily replaced. Supports a three-electrode system for improved control and more accurate measurements Complete Component Set: components include 2x borosilicate glass cell, hollow screws and sealing screws, 2x PTFE cell lid, gasket silicone seal, 1 metal clip, together with 1 copper electrode holder and 1 platinum electrode Interface Between Two Vessels: about 31.3mm OD and 15.2mm ID. These dimensions are consistent across all variants. Manual measurements may vary slightly Optional Gas Sparging Kit: improves gas diffusion by increasing the gas-electrolyte contact area
