Strategic Objectives
• Optimize oxygen mass transfer for maximum cellular productivity.
• Minimize shear stress to protect delicate biological cultures.
• Master the mechanics of impeller design and vessel geometry.
• Implement predictive modeling to reduce expensive pilot-scale failures.
The Core Challenge
Most biological breakthroughs fail during commercialization because the fluid dynamics of a flask do not translate to the industrial scale.
