MAXIMUM ROTATION RATE: 2000 RPM — Never exceed maximum rotation rate when working with rotating electrodes.

TEMPERATURE RANGE: 10°C – 25°C — Electrode damage may occur at temperatures beyond recommended range.

INCOMPATIBILITY WARNING:  soft or fragile disk insert materials (e.g., lead and pyrolytic graphite) are incompatible with this series electrode.

This series of RDE tips may be used with the MSR, ASR, and CPR rotators.

These RDE tips feature a 12.0 mm OD PTFE shroud and PCTFE body (opaque middle section) and are designed with the same thread connections as our standard 12.0 mm OD RDE tips, making it easy to switch between RDE tips using the same shaft.  Designed for advanced electrochemical experiments (e.g. fuel cell electrocatalyst screening), these RDE tips provide the platform you need to accomplish your research goals.

E4TQ 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.

Compatible shafts include AFE3M for use with the MSR rotator, AFE3A for use with the ASR rotator, and AFE3F for non-rotating applications.
