Milligard® PES prefilters provide efficient particulate and bioburden reduction from different process streams. These versatile filters can be used throughout the bioprocessing workflow to increase the throughput capacity of sterilizing filters and improve process efficiency. They can also be used as an alternative to sterilizing filters for bioburden reduction in less critical applications.
Benefits:
- Fast flow and high throughput
- Validated bioburden reduction (1.2/0.2 μm nominal and 1.2/0.45 μm pore sizes only)
- Predictable scalability from small to production scale devices
- Stability: compatible with steam-in place, autoclave and gamma sterilization methods
- Available in our Mobius® single-use library
- Supported by the Emprove® Program
Available Pore Sizes
- 1.2/0.2 µm nominal
- 1.2/0.45 µm
- 1.2/0.8 µm
Available Formats
- OptiScale® 25 capsules – single-use, small-scale tools for process screening and scaling
- Cartridge filters - for pilot and production scale processing
- Opticap® XL and T-line capsules – for bench to production scale
Regulatory Compliance
Milligard® PES filters are designed, developed, and manufactured in accordance with a Quality Management System approved by an accredited registering body to an ISO 9001 Quality Systems Standard and are shipped with a Certificate of Quality. Each filter is supported by documentation to comply with regulatory requirements. For traceability and easy identification, each filter is marked with identifying characteristics.
