Working Principle:
Ultrafiltration membranes separate molecules in a solution based on pore size. The primary mechanism relies on a physical barrier effect, where the membrane’s pores retain molecules and particles of specific sizes. Under external or internal pressure, liquid passes through the membrane surface, while larger molecules (e.g., bacteria, viruses, colloids) are retained on the surface or within the membrane, achieving separation and purification.
Features of Ultrafiltration Membranes:
Diverse Product Options: Available in standard, irradiated, irradiation-compatible, and autoclave-sterilizable types to meet different application needs.
Various Membrane Fiber Sizes: Multiple fiber inner diameters (0.5, 1.0, 1.5 mm) and pore sizes (3 kD-750 kD, 0.1-0.65 μm) to meet different filtration requirements.
High Hydrophilicity and Throughput: Membranes have excellent hydrophilicity and high flux, significantly improving processing efficiency.
Biological Safety: Free from animal-derived components, with low bioburden, meeting the strict requirements of the biopharmaceutical industry.
