Pharmaceutical Grade Polyethersulfone (PES) Filter Cartridges | NSS Series | PUNO Kinda Filtration
Short Description:
Product Overview
PUNO Kinda Filtration R NSS series pharmaceutical-grade filter cartridges are manufactured with Micro-series hydrophilic asymmetric sulfonated PES membrane, featuring broad chemical compatibility (pH 3–11), high flow rate, and long service life. Widely used in biopharmaceutical applications, each cartridge is 100% integrity tested before delivery to guarantee filtration efficiency. It withstands repeated online steam / high-pressure disinfection and fully meets the aseptic requirements of the new version GMP.
Key Features
- Outstanding hydrophilicity, easy wetting, and low protein adsorption
- High porosity via phase transfer technology & unique geometry for improved flow efficiency
