Stirring tasks are most often performed in laboratories using magnetic hotplate stirrers that couple to PTFE magnetic stirring bars in the reaction vessel. Disadvantages of magnetic stirrers include that they are not suitable for highly viscous liquids or for stirring/blending reactions that have high amounts of solid, which can often prove too much for the magnetic coupling.
The DrySyn Vortex system was designed to enable scientists to perform multiple heated or cooled stirred or blended reactions in round bottomed flasks up to 500 mL. Incorporating a powerful gear drive stirrer design the highly reliable DrySyn Vortex has proven especially popular with polymer and material scientists.
To complement the original DrySyn Vortex, Asynt has now developed two further Vortex systems, each incorporating the proven drive gear stirring system and optimised to suit different application needs.
For scientists who need to mix and blend formulations in pots and beakers, Asynt has introduced the Vortex Blend. The Vortex Blend accommodates beaker volumes of up to 1000 mL and many cylindrical containers with a diameter of up to 90 mm. As the Vortex Blend can also be heated, it provides the perfect stirring/blending tool for formulation laboratories.
The Vortex Snowstorm offers an attractive solution for stirred low temperature reaction chemistry. Active temperature control from +150 °C to -30 °C, using a suitable heating/cooling circulator unit, permits unattended operation of up to 12 vials at any one time.
