Repligen MidiKros Hollow Fiber Filter 20 cm Length 0.65 um MPES 0.75 mm FLL X FLL

Repligen MidiKros Hollow Fiber Filter, 20 cm Length, 0.65 µm mPES, 0.75 mm ID, FLL x FLL (D02-E65U-07-N)

The Repligen MidiKros Hollow Fiber Filter (D02-E65U-07-N) is a high-performance single-use tangential flow filtration (TFF) module engineered for pilot-scale, benchtop, and clinical bioprocessing applications. Featuring a 0.65 µm pore size microfiltration membrane composed of modified Polyethersulfone (mPES), this filter delivers superior flux rates, low protein binding, and high volumetric throughput during cell clarification, lysate harvesting, and particle separation workflows. Designed with a 20 cm active path length and 0.75 mm lumen inner diameter (ID) fibers, the module balances shear rate optimization with efficient fluid dynamics. Encapsulated in a clear polysulfone housing with standard Female Luer Lock (FLL) process and permeate port connections, the MidiKros module seamlessly integrates into automated or manual TFF assemblies, providing predictable linear scale-up to larger process-scale filtration systems while eliminating cleaning validation and cross-contamination risks.

Technical Performance & Structural Attributes

• Advanced mPES Membrane Chemistry: Hydrophilized modified Polyethersulfone provides low non-specific binding, excellent chemical resistance across a broad pH range, and minimized fouling tendencies during dense cell harvests.
• Optimized Hollow Fiber Lumen Dimensions: 0.75 mm inner diameter fiber geometry offers an optimal balance between low shear stress on shear-sensitive mammalian or microbial cells and low cross-flow pumping requirements.
• Modular Single-Use Construction: Pre-assembled, potted, and housing-encapsulated design eliminates manual membrane mounting, cartridge cleaning, and water-for-injection (WFI) flushing validation.
• Standardized Luer Lock Connection Ports: Configured with Female Luer Lock (FLL) fittings on both feed/retentate flow-through channels and side permeate ports for secure, leak-free connection to flexible bioprocess tubing circuits.
• Linear Bioprocess Scalability: Identical fluid flow channel height and membrane properties allow direct, reliable scale-up to larger KrosFlo and MaxiKros hollow fiber module formats.
