E6R1 Series ChangeDisk RRDE Tip – Gold Ring

The E6R1 Series Rotating Ring-Disk Electrode (RRDE) tip is a customer favorite – often used for electrocatalyst-based research such as oxygen reduction reaction experiments, for example. This high quality, precision RRDE tip is ChangeDisk style, which means the disk electrode is interchangeable (disks sold separately). This configuration might be useful to researchers who wish to modify the working electrode surface in space-limiting ways (such as annealing in an oven, drying in a desiccator, or preparing in a glovebox, etc.) and for users who want to analyze/image the disk surface after use (for example, AFM or SEM of the disk surface). It may be easier to work with the 5 mm OD x 4 mm thick disk insert independently from the rest of the RRDE tip. Additionally, some users like having one RRDE tip with multiple disk inserts of various preparations and materials, to more quickly drop in a different disk electrode on demand. The gold ring electrode is permanently fixed into position and cannot be removed. The RRDE tip has a PTFE shroud, which has a thermal stability range of 10°C – 25°C. This tip threads into compatible shafts and is not designed to be used by itself. Many other configurations of RRDE tips are available.
