What Are PES Filters?
PES (polyethersulfone) filters are high-precision filtration solutions renowned for their exceptional performance in sterile and aqueous applications. Composed of a naturally hydrophilic asymmetric PES membrane, these filters combine ultra-low protein binding with robust chemical compatibility, making them ideal for critical processes in pharmaceuticals, electronics, and food industries.
How Do PES Filters Work?
Pore Size Precision: Membranes with pore sizes ranging from 0.02μm to 1.0μm (e.g., 0.2μm for bacterial removal) trap particles while allowing liquid flow.
Hydrophilic Nature: The natural hydrophilicity of PES eliminates the need for wetting agents, reducing extractables and ensuring high flow rates.
Double-Layer Design (SteriPure-D): Some models feature dual-layer membranes for enhanced sterilization protection, meeting strict terminal filtration requirements.
Key Advantages of PES Filters :
1. Superior Sterilization Efficiency
2. Chemical & Thermal Stability
3. Economic Efficiency
Critical Applications of PES Filters:
Pharmaceutical Industry: Sterilization of water for injection, APIs, vaccines, and eye drops. The low protein binding of PES ensures minimal product loss in biologic formulations.
Electronics: Ultra-pure water filtration for semiconductor manufacturing, where particle-free fluids are non-negotiable.
Food & Beverage: Sterilization of bottled water, wine, juice, and draft beer, preserving product clarity and shelf life without altering taste.
