Durapore 0.22 µm Hydrophobic Cartridge Filters

Durapore 0.22 µm Hydrophobic Cartridge Filters

Reliable filters for the sterile filtration of gases and liquids
Durapore hydrophobic membrane cartridges are sterilizing-grade filters that provide sterility assurance, high flow rates and high throughput. They are used for sterile tank and gas venting, as well as for the filtration of liquids in small and large volume systems. Durapore 0.22 µm hydrophobic polyvinylidene fluoride (PVDF) membrane reliably eliminates contaminants and microorganisms in sterilizing applications, even at high pH.

Cartridges are robust, resilient and are designed to withstand multiple steam-in-place cycles.


Regulatory Compliance
Filters with hydrophobic Durapore 0.22 µm membrane 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 comprehensive Validation Guide for compliance with regulatory requirements.

For traceability and easy identification, each filter is labeled with the product name and identifying characteristics.


Multiple Formats Available
Durapore cartridge filters are available in four cartridge lengths, from five to thirty inches, and provide a full range of filtration areas to suit every size system. Three connection options are offered for easy adaptation to existing housings.
