MAXIMIZED PERFORMANCE

Gentle on sheer-sensitive molecules

Hollow fibers possess a smooth internal wall and tubular channel geometry, that promotes laminar flow with high flux. The low shear and turbulence of laminar flow helps maintain the integrity of shear sensitive modalities such as lentivirus.

Laminar flow

Flow is primarily straight and streamlined

Turbulent flow

Irregular, chaotic flow creates eddies that change flow in both magnitude and direction

MAXIMIZED PERFORMANCE

Game-changing mPES Chemistry

Directly modified from the PES backbone

Uniquely formulated to provide tight selectivity without sacrificing high flux
Thin selective layer in the inner lumen
Significantly s more porous membrane
Robust design for high-pressure applications
Ideal for Lentivirus, mRNA, pDNA and LNPs
Maximizes recovery
Reduces fouling

规模放大更加简单

中空纤维过滤器组件提供多种尺寸、表面积和膜材质选择，可轻松实现从小体积工艺开发和R&D应用到商品化生产的规模放大。规模放大时，维持过滤流路长度，增加纤维数量，即可提高过滤器的表面积，从而处理更大体积的料液。
