Redox.me – Static Voltammetry Cell

Description

This is a static voltammetry cell with variants for different sample dimensions. The sample is loaded from the bottom via screw mount, while counter or/and reference electrodes are mounted in the lid as either 2-, or 3-electrode configuration. The cell is constructed with materials that are inert to the sample environment (glass and PEEK), and it can be used with FKM/EPDM O-rings or FFKM O-rings for aqueous or organic electrolyte requirements respectively. The construction is gas-tight and inert gas can be bubbled through the electrolyte to remove and exclude contaminants such as air or water. 

Variants

• Water-based electrolyte
• Organic-based electrolyte

Application note
The reference electrode tip should be placed close to the sample surface to ensure a negligible potential drop throughout the electrolyte solution during low-current experiments. Various auxiliary electrodes are suitable for this cell including metal wire and metal plate electrodes as well as carbon-based electrodes (graphite or Glassy Carbon). If a purge gas is used, stop the flow during experiments for better results. For troubleshooting instruction see the redox.me blog post.
