Repligen MiniKros Hollow Fiber Filter 750 kD 1600 cm2 41.5 cm

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

The Repligen S04-E750-05-N is a high-efficiency MiniKros Sampler hollow fiber module designed for pilot-scale Tangential Flow Filtration (TFF). Utilizing proprietary modified Polyethersulfone (mPES) membrane technology, this filter offers exceptional flux rates and high product recovery with minimal non-specific binding. With a 750 kDa MWCO and a significant 1600 cm² surface area, it is the industry standard for the concentration and diafiltration of large biopharmaceuticals, including vaccines, viral vectors, and large multi-meric proteins. The 41.5 cm effective length and 0.5 mm fiber ID are engineered to provide optimal shear conditions, ensuring gentle processing of shear-sensitive biological products while maximizing throughput.

Technical Performance and Design

• Advanced mPES Membrane: The modified Polyethersulfone chemistry provides a hydrophilic, low-fouling surface that outperforms standard PES in both water permeability and product yield (>95% recovery typical).

• Optimized Hollow Fiber Geometry: The 0.5 mm lumen (Fiber ID) creates a precise flow path that reduces concentration polarization, allowing for faster processing of high-viscosity or high-concentration feeds.

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

• Scalable Performance: Part of the Spectrum® filtration line, the S04 series allows for seamless scale-up from R&D to cGMP production by maintaining consistent flow-path lengths and membrane chemistry.
