Polyethersulfone (PES) microfiltration membranes are engineered for superior performance in aqueous solution filtration, effectively removing fine particles, bacteria, and fungi. Available in both supported and unsupported configurations with PP or PET backing layers, these membranes deliver exceptional dimensional stability and handling ease.

• Hydrophilic nature ensures quick and complete wetting
• Low extractables: <2% for minimal contamination risk
• Extremely low protein and drug binding capabilities
• High flow rates and throughput for efficient processing
• Superior retention efficiency across 0.1-15μm pore sizes
• High thermal stability up to 130°C (266°F)
• Consistent lot-to-lot quality with comprehensive testing

Ideal for biological sample preparation with low protein binding, suitable for coarse particulate removal in prefiltration or fine final filtration for clarification applications.

0.1μm and 0.22μm pore sizes provide reliable sterilization of buffers, culture media, additives, and pharmaceutical solutions, with mycoplasma protection.

Fast priming capabilities and air barrier properties make these membranes perfect for IV drip chambers, IV filters, syringe filters, and HMES applications.

Available in versatile formats including flat sheets, discs, and rolls to accommodate various manufacturing requirements. All products conform to ISO sanitary standards for pharmaceutical, healthcare, and life-sciences filtration applications.
