Multi-position overhead stirring for heated and inert reactions<\/h2>\n

The Tornado\u2122 Overhead Stirring System provides powerful and controlled mechanical stirring for up to six round bottom flasks simultaneously<\/strong> when you combine it with the Carousel 6 Plus Reaction Station<\/a>. The system is particularly suited for viscous samples and applications<\/strong> requiring efficient dispersion of delicate solids in solution.<\/p>\n

By using a single overhead stirrer to drive multiple vessels, Tornado can increase stirring productivity while reducing the need for multiple individual stirring setups.<\/p>\n

Key system capabilities<\/strong><\/h3>\n
    \n
  • Mechanical stirring for up to six reaction vessels simultaneously<\/li>\n
  • Rapid heating up to 180 \u00b0C<\/li>\n
  • Water-cooled reflux head for reflux applications<\/li>\n
  • Operation under an inert atmosphere<\/li>\n
  • Compatible with 50 mL, 100 mL, and 250 mL round bottom flasks<\/li>\n
  • Fits all Carousel Stirring Hotplates<\/li>\n
  • Compatible with leading brands of overhead stirrers<\/li>\n<\/ul>\n

    The system can achieve stirring speeds up to 1,000 rpm for low-viscosity samples and supports viscosities up to 10,000 mPas at 500 rpm.<\/p>\n

    Flexible vessel and stirrer configurations<\/strong><\/h3>\n

    The Tornado system supports a range of flask styles and stirrer types to accommodate different reaction requirements.<\/p>\n

    Available flask configurations include:<\/strong><\/p>\n

      \n
    • Standard round bottom flasks<\/li>\n
    • Wide neck flasks<\/li>\n
    • Sidearm flasks<\/li>\n
    • Baffled flasks<\/li>\n
    • 250 mL azeotropic (Dean & Stark) flask option<\/li>\n<\/ul>\n

      Wide neck flasks simplify removal of viscous or solid samples and allow the use of larger stirrer blades. Baffled flasks improve mixing efficiency by disrupting vortex formation during stirring.<\/p>\n

      Users can select from several PTFE stirrer designs, specifically sized for each vessel type:<\/strong><\/p>\n

        \n
      • Centrifugal stirrers<\/li>\n
      • Anchor stirrers<\/li>\n
      • Propeller stirrers<\/li>\n<\/ul>\n

        Heating and stirring performance<\/strong><\/h3>\n

        The Tornado system is heated directly by the stirring hotplate and can be operated using optional digital temperature control and a Pt1000 temperature sensor.<\/p>\n

        Key performance features include:<\/strong><\/p>\n

          \n
        • Up to six heated and stirred reaction positions<\/li>\n
        • Uniform heating through the Carousel Stirring Hotplate<\/li>\n
        • Efficient water-cooled reflux head<\/li>\n
        • Integrated inert atmosphere capability<\/li>\n
        • Individual vessels can be removed independently<\/li>\n<\/ul>\n

          The system uses a tool-free \u201cPinch-Grip\u201d mechanism and sealed stirrer assembly, allowing quick stirrer shaft insertion while supporting gas-tight operation under inert conditions.<\/p>\n

          Improved productivity with a single overhead stirrer<\/strong><\/h3>\n

          Tornado uses one overhead stirrer to agitate multiple vessels simultaneously, helping laboratories reduce equipment costs and save valuable bench space compared to multiple separate stirring setups.<\/p>\n

          The integrated 2-speed drive system (1:1 and 2:1) allows lower torque overhead stirrers to be used effectively with higher viscosity samples.<\/p>\n

          The system integrates directly with existing Carousel 6 Plus setups without increasing the overall laboratory footprint.<\/p>\n

          Safety and ease of use<\/strong><\/h3>\n

          The Tornado system is ideal for simple operation and minimal maintenance.<\/p>\n

          Features supporting safe and convenient use include:<\/strong><\/p>\n

            \n
          • Integral polycarbonate safety guard to prevent accidental contact with rotating components<\/li>\n
          • Optional universal clamp and support stand for additional stability<\/li>\n
          • Easy setup and operation with minimal training<\/li>\n
          • Maintenance-free design<\/li>\n
          • Easy access to individual vessels during operation<\/li>\n<\/ul>\n

            The compact configuration allows multiple heated and stirred reactions to be carried out efficiently while maintaining organised and space-saving laboratory workflows.<\/p>\n
