Tornado Overhead Stirring SystemThe 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 Technical information Videos The range Downloadable resources Case studies Blog 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 Drive System Replaceable toothed belt drive with automatic tensioner Gears 2-speed drive – 1:1 ratio and 2:1 ratio Max RPM 1000 rpm Max viscosity 10,000 cps @ 500 rpm Temperature range Ambient to +180 ºC Glassware 100 ml and 250 ml Working volume 20 ml to 150 ml Tornado Plus Overhead Stirrer RR99951 Tornado Plus Overhead Stirrer Includes drive unit, 6 x stirrer guide mechanisms, stirring motor coupling, stirring motor clamp and polycarbonate safety shield Tornado Support Stand RR99230 Tornado Support Stand Provides support and rigidity with a unique double support rod and brace Pt1000 sensor RR99239 Pt1000 stainless steel sensor with extra-long 345mm probe Allows probe to reach through Tornado unit into Carousel 6 Plus base Other components RR99952 Quick-Thread Stirrer Guide Assembly RR99953 Replacement Tubing for RR99952 110mm (Stirrer Guide to Carousel 6 Plus) Click to download these resources Carousel 6 Plus and Cooled Reaction Stations Brochure Find Out More Tornado Plus Overhead Stirrer System Brochure Find Out More Tornado Plus Instructions Find Out More Radleys International Product Guide Find Out More Tornado allows Beijing Institute Of Fashion Technology to perform six reactions simultaneously Find Out More Tornado brings better consistency to particle size and distribution in heterogeneous chemistry Find Out More Tornado hits Chinese labs Find Out More Tornado, Storm and Carousel 6 Plus work in harmony to help achieve results in China Find Out More Accelerating process optimisation using the Tornado Plus c Find Out More Improving chemistry with Carousel 6 Plus + Tornado system in Shanghai Institute of Pharmaceutical Industry.

Webinar: Stirring viscous reactions - save space and time with TornadoDo you require mechanical stirring on small scale reactions? E.g. viscous materials, heterogeneous mixtures, fragile solids? Join us to see the Tornado Overhead Stirring System in action. Save time and space for the overhead stirring of multiple reactions in round bottom flasks. Watch webinar on demand Webinar: Benefits of overhead stirring on a small scaleJoin us to discuss the benefits of overhead stirring on a small scale: Are you using magnetic or overhead stirring for small scale research and process development? What’s the difference and why does it matter? What factors can be affected when moving from magnetically stirred reactions to overhead and how might this help improve your chemical development and scale up?
