“Using SBE makes my LDH synthesizing process simpler and results in higher crystallinity, which XRD has demonstrated. SBE provides sufficient shear and turnover for distributing all LDH nuclei in the alkali solution.”

MIXR
Magnetic Stir Bar - redesigned from scratch
-
The patent pending 'Daruma' (roly-poly) motion reduces vortex formation and enhances turbulence, greatly improving mass and heat transfer
-
The stir bar spins on a dynamic off-axis rotation (P) relative to the rotational axis of driver magnet (S)
-
-
Insights from CFD simulations have expanded the boundries of magnetic mixing
-
High-shear type: optimized for low viscosity, high RPM
-
High-turnover type: optimized for viscosity up to 1,500 cP
-
Our development approach combines CFD analysis with experimental validation to craft designs that deliver optimal mixing performance.
-
Vorticity: measures fluid rotation; higher vorticity leads to more vigorous mixing
-
Power number: a unitless factor of a design's efficiency in converting mechanical energy into fluid motion
-
Shear rate: how quickly layers of fluid move relative to each other
High-Turnover Design:
The SRS (Streamline Rotational Stirring) design generates 52X more power number than a conventional rod stir bar. This means it moves fluid more efficiently across the entire vessel, making it ideal for mixing thick liquids and speeding up circulation where it's needed most.
High-Shear Design:
The SDA (Shear Driven Action) design creates a shear rate that is 2.7X higher than conventional rod stir bar. This high shear rate helps break apart droplets and breaking up aggregates, and overcoming surface tension, improving the uniformity of the mix.

High-Shear Design
SAN: SDA:
reference impeller
High-shear designs create intense velocity differences within a fluid, generating strong shear forces that enhance mixing. These designs are particularly effective for breaking down particles, reducing droplet sizes, and ensuring uniform reactant distribution.
Key Benefits:
-
Efficient Emulsification: creates stable emulsions
-
Dissolution: reduces blending time
-
Enhanced Micro-Mixing: ensure even distribution of reactants
-
Particle Reduction: breaks apart aggregates
Applications:
-
Chemicals: to improve dispersion of nanoparticles or reagents
-
Food and Beverage: blending additives and coarse emulsions
-
Pharmaceuticals: dispersing active ingredients and uniform mixing
-
Cosmetics: for blending light creams and serums
