Products Description
Polyethersulfone (PES) Membrane Filter Cartridges deliver reliable filtration for aqueous and biologic process streams-ideal where high throughput, chemical compatibility, and sterile performance are required. Designed for consistent retention at 0.03–1.2 µm pore ratings, these cartridges combine stable hydrophilic PES chemistry with tight manufacturing control to protect downstream systems and sensitive products.
