Polyethersulfone Membrane Filters

Polyethersulfone (PES) membrane filters are advanced synthetic filters known for their exceptional thermal and chemical stability, making them suitable for demanding applications in pharmaceutical, biomedical, and food and beverage industries. These filters are constructed from polyethersulfone, a material that provides excellent resistance to acids, bases, and other aggressive solvents, enhancing their durability and lifespan under harsh processing conditions.

PES membrane filters excel in performance with their high flow rates and low protein binding characteristics, which are crucial for sensitive biological processes, including the sterile filtration of therapeutic drugs and vaccines. Their hydrophilic nature allows for easy wetting without the need for surfactants, reducing the risk of contaminant leaching into the sample. Ideal for both aqueous and non-aqueous solutions, PES filters are widely used in ultra-pure water systems and in the filtration of blood and plasma in medical diagnostics, ensuring purity and safety in critical environments.
