Natrix NatriFlo HD-Q Pilot Membrane Filter Sealed NXF-10

Natrix NXF-10 NatriFlo HD-Q Pilot Membrane Filter – High Productivity Q-Chromatography

The Natrix NXF-10 is a pilot-scale membrane chromatography module designed for high-productivity downstream purification. Featuring Natrix HD-Q technology, this module utilizes a high-density quaternary amine (strong anion exchange) functionalized hydrogel within a macroporous membrane matrix. This unique architecture combines the high binding capacity typical of resin-based chromatography with the high flow rates of membrane filtration. The NXF-10 is specifically optimized for "flow-through" applications, providing exceptional removal of DNA, host cell proteins (HCP), and viral contaminants in a single pass. Designed for pilot-scale operations, it provides linear scalability for biopharmaceutical manufacturers transitioning from laboratory development to full-scale production.

Technical Performance and Design

• HD-Q Membrane Technology: The high-density Quaternary Amine chemistry provides superior binding capacity for negatively charged impurities, even at high conductivity and high flow rates.

• Macroporous Hydrogel Matrix: Unlike traditional beads, the hydrogel structure allows for rapid mass transfer and convective flow, significantly reducing processing times and buffer consumption.

• Exceptional Impurity Clearance: Validated for the highly efficient removal of genomic DNA, acidic proteins, and viruses (e.g., MVM, MuLV), ensuring the highest standards of drug substance purity.

• Pilot-Scale Efficiency: The NXF-10 format is engineered to handle mid-sized batches, offering a robust and reliable platform for process validation and scale-up studies.
