3M LifeASSURE PDA Series Filter Cartridge 6 per case PDA020F01BA

We combine two asymmetric polyethersulfone (PES) membrane layers with Advanced Pleat Technology in manufacturing LifeASSURE(TM) PDA Series Filter Cartridges, creating a filter that provides high throughput and fast flow. These filters have applications in pre-filtration and sterilizing filtration in the pharmaceutical, biological, and bioprocess industries where low protein binding is critical. LifeASSURE(TM) PDA Series filters incorporate two layers of polyethersulfone membrane. The upstream layer is highly asymmetric and provides optimized prefiltration capacity for the downstream layer that contains a robust, centrally located, retention zone. 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.
