  • DEPTH FILTER MEDIA
    Publication number: 20240367077
    Abstract: Depth filtration media for the harvest clarification of a feed stream from cell cultures containing a therapeutic biomol-ecule. The depth filtration media is comprised of a sintered mixture of a polymeric adsorbent and a thermoplastic binder and possess ultra-low extractables and do not require pre-flushing prior to use. Further, the materials of construction used for the sintered depth filter media demonstrate a high stability to gamma radiation and are compatible with gamma-based pre-use sterilization processes.
