XyCap PES Capsule Filters are engineered for reliable sterilizing-grade filtration in biopharmaceutical, cell culture, and laboratory applications. Each filter capsule features a dual-layer polyethersulfone (PES) membrane—combining a 0.8 µm prefilter and a 0.2 µm final filter—providing high throughput and low protein-binding characteristics. These filters are ideal for critical liquid processing steps that require sterility assurance and low extractables. The PES membrane offers broad chemical compatibility, fast flow rates, and minimal fouling, making it an excellent choice for aqueous solutions, media, buffers, and downstream intermediates.

Use Cases

• Sterilizing filtration of cell culture media, buffers, and reagents
• Aseptic filtration before final fill in biomanufacturing
• Sterile filtration in QC and lab workflows
• Clarification of process fluids to remove microbial or particulate load
• Final filtration of vaccines, monoclonal antibodies, and protein therapeutics

Product Features

• Dual-layer PES membrane: Integrated prefilter extends life and maximizes flow rate without sacrificing sterility.
• High throughput design: Handles large volumes with low pressure drop.
• Low extractables: Meets stringent purity requirements in regulated environments.
• Sterilization-ready: Gamma-irradiated for direct use in aseptic processes.
• Multiple connections available: Hose Barb for tubing, Tri-Clamp for sanitary systems, Luer Lock for lab-scale use.
• Size 4 capsule format: Compact, scalable design suitable for lab to pilot-scale applications.
