Final Sterile Filtration & Filling

Final sterile filtration and filling are the last steps in the production process and are critical operations to assure product sterility and drug safety for patients. Our Mobius^® single-use systems can be designed to include either single or redundant sterilizing filters and offer manufacturers speed, flexibility, and improved efficiency.   

Filters for Aseptic Filtration

Gas filters are critical to maintaining a boundary between the environment and the aseptic fluid path. Filters containing our sterilizing-grade Millipore Express^® SPG (Sterile, Phobic Gamma) hydrophobic membrane are the preferred choice for gas filtration and venting in single-use applications.

Millipak^® barrier filters contain both hydrophilic and hydrophobic sterilizing-grade Durapore^® membranes, allowing the flow of both liquid and gas. These filters simplify PUPSIT by maintaining the sterility of the system while removing the constrains of a flush bag or a can.

For sterile filtration of aqueous liquids, filters containing our proven Durapore^® polyvinylidene fluoride (PVDF) membrane offer low protein binding and superior robustness. For some processes, our trusted polyethersulfone (PES) Millipore Express^® membrane filters may be a better option.

Our membrane filters are available in multiple filter formats and are fully scalable from small-scale tools to pilot and production scale manufacturing. Capsule filters are compatible with autoclave or gamma irradiation and are also available pre-sterilized for maximum flexibility.

• Millipak^® Final Fill filters contain a Durapore^® PVDF membrane available in multiple pore sizes. The capsule’s stacked disc format minimizes product hold-up volume.
• Durapore^® 0.22 µm filters contain a single layer of 0.22 µm sterilizing-grade PVDF membrane and are robust, low protein binding, and available in multiple filter formats.
• Millipore Express^® SHF (Sterile, High Flux) filters contain a single layer of 0.2 µm sterilizing-grade PES membrane and offer high flux and extremely broad chemical compatibility.
• Durapore^® 5.0 µm PVDF membrane filters remove aggregates and particles from sterile bulk liquids filters and are available in multiple filter formats.

Single-use Filling Assemblies for Fill Finish Processes

Our single-use filling assemblies are custom designed to integrate with various brands of isolator or RABS filling machines. Our Mobius^® experts collaborate with you and your machine vendor to ensure the system is designed to your needs and meets regulatory expectations. Our diverse portfolio of single-use components can be easily integrated into your filling system, and includes:

• Sterile connectors
• 2D header bags up to 50 L
• Dosing pump tubing
• Molded TC manifolds
• Beta bags
• Single-use filling needles

The result is a single-use final fill system that’s ready to use out of the box, featuring modular, fully optimized assemblies. These systems are replicable, scalable, and simplify technology transfer across multiple sites.

Please contact your local representative for help with designing a custom final filtration and filling assembly.
