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
Key features

Uses a single overhead stirrer to agitate up to six 250 ml flasks
Choice of centrifugal, anchor and propeller PTFE stirrers, specifically sized for each vessel
Choice of flask sizes and styles with wide neck option:
- Wide neck flasks allow easier removal of viscous and solid samples and the use of larger stirrer blades.
- Baffles improve stirring by disrupting the creation of a vortex
Tool-free ‘Pinch-Grip’ mechanism and sealed stirrer system allows easy stirrer shaft insertion and operation under an inert atmosphere
Compatible with all leading brands of overhead stirrer
Heated directly by the stirring hotplate with optional digital control and Pt1000 temperature sensor
Integral polycarbonate safety guard
Provides up to six heated (max +180 ˚C) and stirred reaction positions
Universal support stand gives added stability
Integrates with existing Carousel 6 Plus without increasing footprint
Fits on all Carousel Stirring Hotplates
Accepts 50 ml, 100 ml and 250 ml round bottom flasks (sidearms and baffled flasks available)
Individual vessels can be removed easily
Easy to operate and set-up with minimal training time
2-speed drive (1:1 and 2:1) allows lower rated stirrers to be used for higher viscosity liquids
250 ml Azeotropic (Dean & Stark) flask option. Here with dropping funnel and centrifugal PTFE stirrer
Fits directly onto the Carousel 6 Plus without the use of tools.

Choice of flask sizes and styles, including wide neck option
Wide neck flasks allow easier removal of viscous and solid samples and the use of larger stirrer blades. Baffles also improve stirring by disrupting the creation of a vortex.

Universal Support Stand aids stability
This heavy duty, stainless steel and aluminium stand provides the added support needed for stable operation of the Tornado. Tool-free design is easy to assemble.

Choice of PTFE Stirring Paddles
Choose from centrifugal, anchor and propeller PTFE stirrers, specifically sized for each vessel. Custom formats available on request.
