(water to shampoo)
High-turnover designs prioritize rapid fluid circulation within a vessel, maximizing the exchange of materials between different regions. This ensures faster homogenization, improved reactant contact, and efficient bulk mixing for a wide range of applications.
Key Benefits:
-
Rapid Circulation: achieves fast homogenization
-
Enhanced Mass Transfer
-
Efficient Bulk Mixing: reduce dead zones
-
Versatile Adaptability: effective across varying viscosities and vessel sizes
Applications:
-
Paint and Coatings: uniform dispersion of pigments and additives
-
Slurries: homogenizes solid-liquid mixtures in ceramics applications
-
Solid Catalysis: improves reactant-catalyst contact without breaking substrate
-
Chemical Processing: bulk polymerization reactions
-
Advanced Materials: faciliate dispersion of nanofibers or other fillers in resin

Innovation 2
CFD Simulation-Optimized Design
High-Turnover Design:
The SRS (Streamline Rotational Stirring) design generates 52X more power number and 1.5X more vorticity than a conventional rod stir bar.
The higher vorticity of SRS02 at the macroscale leads to more vigorous mixing, moving fluid more efficiently across the entire vessel and making it ideal for mixing thick liquids and accelerating circulation where it’s needed most.

▲ Fluid flow pattern of propeller impeller and SRS02 (up-pumping)
The unique blade design of the SRS, inspired by propeller impellers, generates a hybrid axial/radial flow that ensures uniform, dead-zone-free mixing in all directions.
The SRS can handle viscosities from 1 cP to 1,500 cP, accommodating fluids from water to gels. Its patented precession motion enables a distinctive dual-axis stirring behavior, effectively breaking stable, symmetrical flow fields and significantly enhancing macroscopic fluid circulation. Compared with conventional single-axis magnetic stirring, the SRS not only drives flow in bottom and dead-zone areas but also promotes three-dimensional turnover throughout the vessel, effectively reducing sedimentation and stratification.
Usage example
This video presents three different utility patents.
FLXR’s propeller-like SRS02 incorporates a unique dynamic off-axis motion, generating complex flow dynamics and enhancing mixing efficiency.
In this video, 0.05 g of powder pigment is added to epoxy to evaluate the mixing efficiency of two different magnetic stir bars.
The results show that the SRS achieves a full turnover 10 times faster than the rod.
