3M™ LifeASSURE™ PDA Series Filter Cartridges combine two asymmetric polyethersulfone (PES) membrane layers with Advanced Pleat Technology. Our filters have applications in sterilising filtration of biological solutions where low protein binding is critical.
Get high throughput and fast flow with 3M™ LifeASSURE™ PDA Series Filter Cartridges. Incorporating two layers of polyethersulfone (PES) membrane, the highly asymmetric upstream layer provides prefiltration capacity for the downstream layer, which is also asymmetric. Together, the membrane layers create a gradient membrane pore morphology that provides relatively high contaminant capacity and fast flow rates in a sterilising grade membrane filter. 3M LifeASSURE PDA Series filter Cartridges also feature our innovative Advanced Pleat Technology construction that helps extend service life. This design technology is intended to increase the useful surface area while maintaining open flow paths between media pleats. We manufacture LifeASSURE PDA Series filter cartridges using all-polypropylene structural components (end caps, adapters, media support, inner core and outer cage). We offer LifeASSURE PDA filter cartridges in multiple lengths to match the dimension and sealing requirements for most cartridge housings currently available. Engineered for Quality and Reliability Our 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. We ship all LifeASSURE PDA cartridge and capsule filters with a Certificate of Quality affirming compliance with manufacturing quality specifications. Additionally, supporting Drug Master File (DMF) documentation is on file with the United States Food and Drug Administration (FDA) and a complete LifeASSURE PDA Validation Guide is available upon request. Meeting Your Scale-Up Needs 3M are pleased to offer a full range of LifeASSURE PDA sterilising-grade filters to meet your scale-up process needs. This includes pre-sterilised or sterilisable disposable capsules in various sizes as well as full-size cartridges. We also offer filter discs when even smaller membrane surface areas are required.
