Durapore® Multimedia filters combine a 0.22 µm hydrophilic Durapore membrane with an upstream Milligard® prefilter media, providing sterility assurance, high flow rates and extended throughputs, low extractables, and broad chemical compatibility. The combination of prefiltration media and final sterilizing membrane in one filter results in process compression and improved economics.
Multimedia cartridge filters are ideally suited for processes that require maximum pressure differentials. Cartridges are robust, strong, resilient and are designed to withstand multiple steam-in-place cycles.
Multimedia filters are designed, developed, and manufactured in accordance with a Quality Management System approved by an accredited registering body to an ISO® 9000 Quality Systems Standard and are shipped with a Certificate of Quality. Each cartridge filter is integrity tested during manufacturing and is supported by a Validation Guide for compliance with regulatory requirements.
For traceability and easy identification, each device is marked with the product name and identifying characteristics.
