Innovative Vertical-Wheel® Technology

​Unique features include:

• Vertically-orientated, Wheel-shaped impeller is a departure from traditional  horizontal impeller designs that create tornado-like mixing

• Long Wheel radius, peripheral paddles, and the rounded bottom of U-shaped vessel contribute to sweeping yet gentle fluid flow
• Oppositely-oriented internal vanes contribute to the “cutting and folding” axial fluid flow pattern through center of Wheel  
• Wheel is enclosed inside single-use vessel and rotates freely around a stationary shaft
• ​​Fast, efficient mixing performance with uniform particle suspension and dispersion

True Scalability
​

• Consistent mixing performance with low shear stress, from 50 mL to 500 L working volumes, using the same Vertical-Wheel mixing mechanism

• The result is true, predictable scalability: the same mixing parameters (e.g. volumetric power input) that work at 50 mL can be applied at 500 L to achieve a similar microenvironment

• Vertical-Wheel technology facilitates cost effective, high-throughput screening at the representative benchtop level before scaling up to larger volumes for clinical and commercial manufacturing
