Cyclone magnetic stirrer drive

Buchi ‘cyclone 075’ is a complete stirrer drive, that incorporates a magnetic coupling and a built-in motor. The compact drive unit is fixed onto the cover plate of the reactor with an NS29/32 ground joint.

The cyclone controller enables stepless stirrer speed adjustment of the motor. Stirrer speed and torque can be transferred via a RS 232 interface.
