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.

Tornado

  • 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
Tornado

  • 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
Tornado Overhead Stirring System

  • 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

  • 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

Webinar: Benefits of overhead stirring on a small scale

Join 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?
