Brochure: LifeASSURE™ PDA Series Sterilizing Grade PES Membrane Filters

3M Purification Inc.'s 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 Membrane Technology
LifeASSURE PDA series filters incorporate two layers of unique 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.
