Flexsafe® Pro Mixer Small Volume

The Flexsafe® Pro Mixer 5 L | 10 L | 20 L addresses critical challenges in small-scale bioprocessing through its innovative single-use mixing technology. This benchtop system delivers powerful mixing capabilities (0-750 rpm) while maintaining gentle, low-shear conditions essential for processing sensitive biologics and complex formulations.

The modular design features a single base unit that accommodates three different bag holder sizes, available in both stainless steel and plastic configurations. This flexibility enables seamless adaptation to varying batch requirements from 1 to 20 L working volumes. The same proven mixing technology scales predictably up to 3,000 L, facilitating straightforward process transfer from development to commercial manufacturing.

Key applications span the entire bioprocessing workflow, including media and buffer preparation, clarification and harvest operations, and final drug substance formulation. The levitating impeller design minimizes mechanical stress on shear-sensitive products, preserving protein integrity and maintaining biological activity throughout processing.

The single-use Flexsafe® mixing bags eliminate contamination risks associated with traditional cleaning and validation protocols. Each bag features a cubical design with strategically positioned ports for efficient fluid handling and incorporates a 76 mm LDPE impeller for optimal mixing performance. The system operates reliably across temperatures from 2-30°C and accommodates various viscosities through its high-torque motor design.

Technical specifications include comprehensive control integration with analog and digital I/O capabilities, enabling seamless incorporation into automated bioprocessing environments. The compact footprint (468 x 452 x 244 mm) and 11.5 kg weight facilitate laboratory integration while maintaining industrial-grade construction standards.

For process development teams requiring predictable scale-up characteristics and clinical production facilities demanding contamination-free operations, the Flexsafe® Pro Mixer delivers consistent performance across multiple processing stages. The combination of powerful mixing capability and gentle product handling makes this system particularly valuable for biologics manufacturing, where maintaining product quality while achieving efficient processing remains paramount.
