This disk insert is used for a variety of electrochemical applications. Namely, the disk insert is used as the working electrode in ChangeDisk Rotating Disk (RDE) and Rotating Ring-Disk (RRDE) electrodes. This 5 mm OD x 4 mm thick disk insert has been precision machined to exactly fit Pine Research 5 mm ChangeDisk electrode tips. One side of the disk is polished, and its opposite site is not and has a slight bevel for optimal insertion and removal from the ChangeDisk tip. We offer many different materials and even different sizes on request (not stocked). Contact us for custom disk materials, sizes, and finishes.

Consumable U-Cups!
The PTFE U-Cup is a consumable product for the ChangeDisk RDE and RRDE tips. To ensure proper operation and longevity of the tip, Pine Research recommends replacing the U-Cup every 4-5 times you perform a ChangeDisk operation. Permanent, irreversible damage to the tip will result if the U-Cup is not regularly changed. Consider purchase a backup supply when ordering a new ChangeDisk RDE or RRDE tip.
