PPD/GS Capsule Filters: Pleated Polypropylene Depth Media
By Critical Process Filtration

Single-use processing demands filtration solutions that deliver both performance and compatibility without adding complexity. Gamma-stable depth filtration offers a practical approach for prefiltering critical pharmaceutical and healthcare liquids, combining high particulate retention with materials designed to withstand irradiation. Hydrophilic polypropylene media supports efficient flow while capturing large contaminant loads, helping protect downstream filters and extend overall system life.
With high retention efficiency and a wide range of pore sizes, this approach adapts to diverse applications — from buffers and intermediates to water purification and medical formulations. Its scalable design, from compact mini-capsules to larger formats, enables consistent performance across development and production environments. Low extractables and regulatory compliance further support use in sensitive workflows where product integrity is essential.
For teams working with single-use systems, optimizing prefiltration with gamma-stable components can improve consistency, reduce risk, and support more streamlined operations.
