Repligen MiniKros Hollow Fiber Filter Sterile 750 kDa 1600 cm2

Repligen MiniKros S04-E750-05-S Hollow Fiber Filter (Sterile, 750 kDa, 1600 cm2)

The Repligen S04-E750-05-S is a high-performance MiniKros Sampler hollow fiber module designed for pilot-scale Tangential Flow Filtration (TFF) under aseptic conditions. Utilizing proprietary modified Polyethersulfone (mPES) membrane technology, this filter offers exceptional flux rates and high product recovery with minimal non-specific binding. This "S" designation indicates the module is supplied Gamma Irradiated (Sterile), providing a closed-system solution for sensitive bioprocessing workflows. With a 750 kDa MWCO and a significant 1600 cm2 surface area, it is the industry standard for the concentration and diafiltration of large biomolecules, including vaccines, viral vectors, and nanoparticles.

Technical Performance and Design

• Aseptic Ready (-S): Gamma irradiated for immediate integration into sterile flow paths, eliminating the need for user-led sanitization cycles prior to processing sensitive biological samples.

• Advanced mPES Membrane: The modified Polyethersulfone chemistry provides a hydrophilic, low-fouling surface that maximizes water permeability and ensures high product yield (>95% typical recovery).

• Optimized Hollow Fiber Geometry: The 0.5 mm fiber ID (lumen) provides a precise flow path that balances shear forces with throughput, making it ideal for shear-sensitive viruses and large proteins.

• 750 kDa Selective Barrier: Engineered for "Large-Molecule" Ultrafiltration. It effectively retains viral particles (AAV/Lenti) while allowing smaller host-cell proteins and buffer components to pass into the permeate.
