Reliable filters for the sterile filtration of gases and liquids
Durapore hydrophobic membrane cartridges and capsules 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.
Opticap XL capsule filters eliminate the time and expense associated with assembling, cleaning, and validating stainless steel housings. The capsule patented design allows unparalleled thermal and hydraulic stress resistance, resulting in reliability, high confidence in the sterility process and improved cleanliness.
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 capsule 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
Opticap XL capsule filters with hydrophobic Durapore membrane are available in multiple filtration areas, providing an optimal choice for every application.
