E8R4 Series Fixed-Disc High-Efficiency Rotating Ring Electrode
Glassy carbon (GC) disc, gold anel (Au) | PTFE Separator, PEEK Cover
The E8R4 series Fixed Ring Rotating Disc Electrode (RRDE) tip is often used in electrocatalyst-based research, such as oxygen reduction reaction (ORR) experiments.
This high-quality, precision RRDE tip is a fixed disc tip, meaning the disc electrode is fixed in position and cannot be removed or changed.
The ring electrode is also permanently fixed in position and cannot be removed. The RRDE tip features a PTFE ring-disc separator, which can contribute to hydrophobicity in drop molding procedures.
It also features a PEEK sheath, which provides increased thermal stability. This tip threads onto compatible shafts and is not designed to be used alone. Many other RRDE tip configurations are available.

Important:
Maximum Rotational Speed: 3000 RPM
Never exceed the maximum rotational speed when working with rotating electrodes.
Maximum Rotational Speed:
All rotating electrodes, including RDE, RRDE, and RCE, have a maximum rotational speed assigned. This maximum rotational speed is specific to each electrode series. Do not exceed the maximum rotational speed when working with rotating electrodes.
Shafts Sold Separately:
Given the wide range of electrodes we offer, with each series requiring one of several rotating shafts, shafts must be purchased separately for MSR and MSR evo rotators. Refer to the RDE, RRDE, or RCE specifications to determine which shaft is compatible.
Compatibility Notice:
This product is only compatible with the MSRX (AFMSRX), MSR (AFMSRCE), MSR evo (AFMSR24), and WaveVortex 10 (AF01WV10) electrode rotators.
Thermal Stability Range: 10°C–80°C:
Electrodes may be damaged at temperatures above the recommended range. This range is provided for electrodes with PEEK sheaths.
