|Filters with Milligard® PES Membrane - Wetting Instructions, Integrity Testing, Sterilizing and Drying Guidelines|
Milligard® PES filters are designed for effective bioburden control and reliable removal of particles from a broad range of fluid streams. These membrane based filters can provide validated bioburden reduction in applications where sterilizing filtration is not required. They can be used at different stages in a bioprocess production train enabling more efficient performance of sterile filters and protection of other unit operations.
- 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
- High thermal stability: compatible with steam-in place and autoclave sterilization methods
- Caustic stable
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 cartridge filter is supported by documentation to comply with regulatory requirements. For traceability and easy identification, each filter is marked with
Available Pore Sizes for Bioburden
- 1.2/0.2 μm nominal
- 1.2/0.45 μm
Available Pore Sizes for Particulate Reduction
- 1.2/0.8 μm
Single-use, Small-Scale Tool for Process Screening and Scaling
OptiScale® single-use capsule filters are ideal for quickly evaluating performance of different prefilters with various process streams.
For Pilot and Production Scale Processing
Our cartridge filters are designed for use in stainless steel housings and provide high throughput and minimal differential pressure. These cartridges are robust, strong, resilient and are designed to withstand multiple steam-in-place cycles. A full range of filtration areas and connection options are available for maximum flexibility.
