The E4TQ ChangeDisk rotating disk electrode (RDE) tip is related to the E3 series RDE tips, but instead of a fixed, permanently-mounted disk electrode, users can install and change the disk as desired.  This electrode consists of three main parts: the body, the holder, and the disk contact pin.  The disk contact threads into the Standard RDE shaft and makes backside contact with an installed disk electrode.  The body screws onto the Standard RDE shaft to secure the holder in place.  The holder is precision-machined from PTFE, and fits into the body with two O-rings.  The holder accepts 5 mm OD disk inserts, from 4 mm thick to 1.5 mm thick.  Users must also purchase the E4TQ Series ChangeDisk Toolkit for installing and removing disk inserts.  This ChangeDisk RDE tip is compatible with the legacy CPR rotator shaft, and with current MSR family electrode rotators when using the Standard RDE shaft.

Maximum Rotation Rate: 3000 RPM

Never exceed maximum rotation rate when working with rotating electrodes.

Maximum Rotation Rate

All rotating electrodes, including RDE, RRDE, and RCE, have an assigned maximum rotation rate. The maximum rotation rate is specific to each electrode series. Do not exceed the maximum rotation rate when working with rotating electrodes.

Thermal Stability Range: 10°C - 25°C

Electrode damage may occur at temperatures beyond recommended range. This range is provided for electrodes with PTFE or PCTFE shrouds.

Electrode Rotator Compatibility Notice

This product is only compatible with the ASR (AFASR), MSRX (AFMSRX), MSR (AFMSRCE), MSR evo (AFMSR24), and CPR (AFCPRB/AFCPRBE) electrode rotators.

Tight Interference Fit!

The opening diameter of the disk holder in this ChangeDisk electrode tip, designed for use with 5 mm OD disk inserts, is specified as 4.724 - 4.775 mm. This is by design and not a manufacturing error. The tight interference fit is required to make a proper seal between disk and shroud. Always use the E4TQ Toolkit to propertly install a disk. The fit is very tight.

Incompatible with Softer Materials

Soft or fragile disk insert materials, such as pyrolytic graphite and lead, are incompatible with this electrode.

E4TQ Series ChangeDisk Rotating Disk Electrode is a single product with individual parts that may be purchased separately. The data below aggregates the specifications for each part in this product.
