This product is developed for precise filtration in laboratory and industrial settings, featuring polyethersulfone (PES) microporous membrane construction. The material offers low protein binding and high chemical resistance, making it suitable for sample preparation, solvent filtration, and microbiological analysis. Available in diameters from 13 mm to 90 mm and pore sizes of 0.22 µm, 0.45 µm, and 0.8 µm, these membranes balance flow rate with particle retention across various applications. The membranes are supplied in standardized box quantities, enabling consistent use in routine filtration workflows. Their thermal stability and mechanical integrity support compatibility with common aqueous and organic solvents. This product is particularly relevant for research requiring reliable, reproducible filtration performance without cross-contamination. The specifications reflect a typical microporous filter membrane suited for both analytical and preparative procedures.
