PPS Filters: Double Layered PES Membrane
By Critical Process Filtration

Sterile filtration in high-value applications demands a balance of precision, throughput, and product compatibility. Double-layer membrane design delivers enhanced security by combining strong retention with consistent flow performance, even across varying process conditions. Hydrophilic polyethersulfone membranes provide reliable filtration for aqueous solutions while minimizing interaction with sensitive components such as proteins and preservatives. This low-binding characteristic helps preserve product quality while maintaining efficiency.
With a broad pore size range and scalability from laboratory to full production, this filtration approach adapts to diverse workflows, including vaccines, biologics, and high-purity water systems. Validated performance, low extractables, and compatibility with common sterilization methods further support use in regulated environments.
Teams focused on consistency and contamination control benefit from dual-layer membrane designs that provide greater filtration stability and reliability. Learn more about the design opportunities, and click to read.
