LifeASSURE™ PLA Series Filter Cartridges encompass two important design elements-multi‐zone microporous membrane and Advanced Pleat Technology to offer prefiltration protection of final membrane filters. These filters have applications in prefiltration and clarification in the pharmaceutical, biological and bioprocess industries.

• Multi-zone microporous nylon membrane offers maximum membrane protection and increased contaminant capacity
• Advanced Pleat Technology construction allows maximum fluid and contaminant access to filter surface area for highest throughput
• 100% Integrity tested prior to release ensures consistent performance to specification
• Multi-zone microporus membrane construction
• Advanced pleat technology design

We incorporate our multi‐zone microporous membrane technology into our LifeASSURE™ PLA Series filter cartridges. 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.

LifeASSURE™ PLA Series filter cartridges 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.

We manufacture LifeASSURE™ PLA Series filter cartridges 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).
