Our 1.2 micron Polyethersulfone (PES) membrane diaphragm is engineered for disposable filtration devices, offering superior performance in medical, pharmaceutical, and research applications. Available in various formats including flat sheets, discs, and rolls with customizable dimensions.

• Hydrophilic membrane with excellent wettability
• Low extractables: <2% for minimal contamination
• Low protein and drug binding properties
• High flow rate and retention efficiency
• Exceptional thermal stability up to 130°C (266°F)
• Consistent lot-to-lot quality assurance
• Excellent chemical resistance with pH range 1-14

• Pharmaceutical filtration processes
• I.V. filters for infusion and transfusion therapy
• Biologics, buffer, serum, reagents and cell culture media filtration
• Protein separation and monoclonal antibodies
• Vaccine production and microbiological fluid filtrations
• Ophthalmics and medical device manufacturing

The PES membrane features an asymmetrical pore structure with largest openings on one side and smallest on the opposite. For optimal throughput, orient the dull/matte side (largest pores) upstream. For microscopic analysis, orient the shiny side (smallest pores) upstream to capture particles on the surface.

XINNA provides comprehensive technical support and service to ensure optimal performance with our PES membrane products. Our technical team is available to assist with application-specific requirements and customization needs.
