Tornado Overhead Stirring System

The Tornado allows powerful, controlled mechanical stirring of up to six round bottom flasks when combined with the Carousel 6 Plus Reaction Station; offering unrivalled stirring for both viscous samples and for the dispersion of delicate solids in solution.

Integrates with Carousel 6 Plus to provide heated and stirred reactions
Rapid heating to 180 ˚C, with water-cooled reflux head
Perform reactions under an inert atmosphere
Accepts 50 ml, 100 ml and 250 ml round bottom flasks

Uses a single overhead stirrer – save space and money compared with multiple set-ups
Compatible with all leading brands of overhead stirrer
2-speed drive allows overhead stirrers with less torque to be used for higher viscosities

Stir to 1,000 rpm in low viscosity
Max. viscosity 10,000 mPas at 500 rpm
Integral polycarbonate safety guard prevents accidental contact with rotating parts
Optional clamp and stand provides added stability during operation

Since using the Tornado system we can simultaneously carry out several reactions. This has greatly increased our work efficiency and the Carousel 6 part of the system also offers parallel magnetic stirring as well.Professor Chen Biqiang, College of Life Science and Technology, Beijing Institute of Chemical Technology
