MAXIMUM ROTATION RATE: 3000 RPM -- Never exceed maximum rotation rate when working with rotating electrodes.

This product has been discontinued. New customers should purchase our new E6 Series RRDEs instead of the older MTI Series.

Disk OD = 6.0 mm; Ring ID = 7.50 mm; Ring OD = 8.50 mm; Shroud OD = 15.0 mm
Collection Efficiency (theoretical) = 24%
Accepts disk inserts 6.0 mm OD x 4.0 mm thick (made to order)
Compatible with MSR rotator only

Existing owners of MTI Series RRDE tips can expect continued support for the lifetime of their electrodes. However, most replacement parts (as listed below) will be available from Pine only on a made to order basis.
Existing owners of MTI34 Series RRDE tips are encouraged to upgrade their RRDE tips to accept readily available standard 5.0-mm disk inserts. The upgrade hardware (part number ACMTI3680DCT) essentially converts an MTI34 tip to an MTI36 tip. The MTI36 tip can then be used with 5.0-mm disk inserts. Traditional 6.0-mm disk inserts will continue to be available only on a made to order basis.
