3M™ LifeASSURE™ PLA series filters are 3M's latest advance in membrane filter technology. Encompassing two leading-edge processes, multi-zone microporous membrane manufacture and Advanced Pleat Technology (APT) pleating construction, the LifeASSURE™ PLA series filters offers unmatched protection of final membrane filters, as well as exceptionally long service life. Designed with pleated Nylon 6,6 membrane in an all-polypropylene construction, LifeASSURE™ PLA series filters are ideally suited for a wide range of prefiltration and clarification applications in the pharmaceutical, biological, and bioprocess industries.
Multi-zone Microporus Membrane Construction
We incorporate our multi‐zone microporous membrane technology into our LifeASSURE™ PLA Series filter capsules. This technology allows great flexibility in creating a multi‐zone membrane that offers excellent contaminant holding capacity while maintaining high retention efficiency. LifeASSURE™ PLA series filter membrane consists of an “open” zone on the upstream side of the membrane and a “tighter” zone on the downstream side. In effect, the open zone acts as a prefilter by capturing larger particles and colloids.
Advanced Pleat Technology Design
LifeASSURE™ PLA Series filter capsules also feature our Advanced Pleat Technology (APT) design for extended service life. This design technology is intended to increase the useful surface area while maintaining open flow paths between media pleats.
Performance Engineered for Quality and Reliability
We manufacture LifeASSURE™ PLA Series filter capsules using all polypropylene structural components (end caps, adapters, media support, inner core and outer cage). The 3M Purification Inc. Quality Management System is approved by an accredited registering body to the ISO 9001:2008 and ISO 13485:2003 Quality Management Systems, and the cartridges are 100% forward flow integrity tested prior to shipment. All LifeASSURE PLA Series filters are shipped with a Certificate of Quality affirming compliance with manufacturing quality specifications. Supporting Drug Master File (DMF) documentation is on file with the United States Food and Drug Administration (FDA).
