The DrySyn Vortex system is an innovative laboratory tool designed for powerful, parallel overhead stirring of viscous materials in round bottom flasks using a single overhead stirring motor. It is especially useful when traditional magnetic stirring proves insufficient or unsuitable. Developed with the needs of synthetic chemists in mind, the DrySyn Vortex provides an efficient, robust, and safe means of achieving high-performance stirring across multiple reactions simultaneously.
At its core, the DrySyn Vortex enables three-position overhead stirring, allowing for up to three flasks (each up to 500 mL), to be stirred in parallel using a single overhead motor. This system is fully compatible with the popular DrySyn MULTI range, accommodating flask inserts of 100 mL, 250 mL, and 500 mL. Furthermore, by combining the Vortex with either a standard hotplate or a temperature-controllable base, users can carry out experiments at precise and stable temperatures, whether heating or cooling is required.

Why choose overhead stirring for round bottom flasks?
One of the main reasons to opt for overhead stirring over magnetic stirring is its superior power, particularly when handling high-viscosity samples or larger volumes. Magnetic stirrer bars often struggle with thick solutions, and the grinding forces they introduce can be damaging to delicate materials such as crystals or particles in suspension.
In contrast, overhead stirring mixes with a stirring shaft, providing more vigorous and consistent mixing without the abrasive action of a spinning bar. For researchers working on parallel synthesis, scale-up, or formulation development, the ability to stir multiple reactions simultaneously with identical stirring power and control can drastically improve throughput and reproducibility.
The DrySyn Vortex is also ideal for situations where magnetic stirring simply cannot achieve the desired mixing intensity, or where motor-driven agitation is preferred for safety or technical reasons.

How the DrySyn Vortex works:
The DrySyn Vortex operates through a cleverly engineered and robust mechanical gearbox. This central mechanism distributes torque from a single overhead stirrer to three separate stirring positions. A built-in reduction drive enhances torque delivery, making it suitable for viscous materials or enabling use with lower-torque motors.
Switching between direct drive and reduction drive is quick and simple, allowing the user to adapt to varying experimental needs. Whether you’re using a powerful overhead stirrer or a lighter-duty model, the Vortex can provide consistent, reliable stirring across all three positions.

The DrySyn Vortex has an optional base setup which is ideal for sub ambient temperature control
Conclusion:
The DrySyn Vortex is an effective and practical solution for parallel overhead stirring of round bottom flasks. It combines flexibility, efficiency, and control, making it a valuable asset for any laboratory involved in chemical synthesis, formulation work, or scale-up development. By enabling efficient heating or cooling and allowing precise control over stirring conditions, the Vortex ensures optimal results across a wide range of challenging applications.
