Product Description
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
