MAXIMUM ROTATION RATE: 2000 RPM — Never exceed maximum rotation rate when working with rotating electrodes.
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 3-4 times you perform a ChangeDisk operation. Permanent, irreversible damage to the tip will result if the U-Cup is not regularly changed.
TEMPERATURE RANGE: 10°C – 80°C — Electrode damage may occur at temperatures beyond recommended range.
CHEMICAL INCOMPATIBILITIES: Concentrated Strong Acids — Damage or discoloration may occur.
Polishing PEEK-shrouded electrodes is best accomplished using a mechanical polisher. Other shroud materials are available upon request.
This series of RDE tips may be used with the WaveVortex 10, MSR, and ASR electrode rotators.
These RDE tips feature a 15.0 mm OD PEEK shroud and are designed with the same thread connections as our standard 15.0 mm OD RRDE tips, making it easy to switch between RDE and RRDE configurations using the same rotator shaft. Designed for experiments like fuel cell electrocatalyst screening, these RDE tips provide the platform you need to study catalyst behavior over a range of temperatures.
E5TQPK Series RDE tips feature removable disk inserts (sold separately). Standard metal disk inserts offered by Pine Research are 5.0 mm OD x 4.0 mm thick and are fabricated from gold, platinum, or glassy carbon; however, disks may be made from other materials or dimensions upon request. A toolkit (sold separately) and polishing kit (sold separately) are also required to change and polish the metal disk insert between experiments.
Unlike some Fixed-Disk electrodes with a PEEK shroud, the E5TQPK Series RDE tips use a PTFE U-cup that surrounds the disk insert and sits between the disk and PEEK shroud. The PTFE U-cup provides a hydrophobic barrier around the disk to enable easier thin film deposition.
Compatible shafts include AFE6MB, AFE6M, and AFE5M for use with the MSR rotator, AFE6A and AFE5A for use with the ASR rotator, and AFE5F for non-rotating applications. The E5TQPK Series RDE tips are also compatible with the WaveVortex 10 Electrode Rotator.
