Sterilizing Grade Filters: Small Molecule & API Applications

3M Purification's sterilizing grade fitlers feature and innovative Advanced Pleat Technology design for extended service life. This design technology maximizes the useful surface area of the filter while maintaining open flow paths between media pleats. By employing Advanced Pleat Technology design, the LifeASSURE series filter provides lower pressure drops, longer service life and lower overall filtration costs.

LifeASSURE PDA Series - Sterilizing Grade Membrane Filters 

LifeASSURE™ PDA series filter combines two asymmetric polyethersulfone (PES) membrane layers together with proprietary Advanced Pleat Technology (APT) design. This design results in a robust filter that is optimized for both high throughput and fast flow applications while offering 0.2 µm absolute rated filtration for sterilizing performance. The unique hydrophilic polyethersulfone membrane wets easily for integrity testing and is ideal for applications where low protein binding is critical. LifeASSURE PDA series filters incorporate two layers of unique polyethersulfone membrane. Both membrane layers are asymmetric and together result in a filter with multiple filtration zones providing extremely high contaminant capacity, fast flow rates and reliable sterilizing filtration performance.

LifeASSURE™ PSA Series - Sterilizing Grade Nylon Membrane Filter

Encompassing two leading-edge processes, multi-zone microporous membrane construction and Advanced Pleating Technolog (APT) design, LifeASSURE™ PSA Series filters offer robust 0.20 and 0.10 micron absolute-rated filtration and exceptionally long service life. Designed with two layers of pleated Nylon 6,6 membrane in an all-polypropylene cartridge construction, LifeASSURE PSA Series filters are ideally suited for a wide range of sterilizing applications in the pharmaceutical, biological, and bioprocess industries.

LifeASSURE™ SP Series - Sterilizing Grade Filter Cartridges & Capsules

LifeASSURE SP series sterilizing grade filters and capsules are validated for absolute bacteria retention and provide reliable sterile filtration performance. In addition to a fixed bacteria retentive pore structure, LifeASSURE SP series membrane is charge modified to provide enhanced reduction of negatively charged biological contaminants such as endotoxin, virus and nucleic acid fragments. The combination of a validated bacteria retentive membrane, together with enhanced reduction of negatively charged contaminants, make LifeASSURE SP series membrane an ideal choice for pharmaceutical and iopharmaceutical sterilizing applications.
