3M™ LifeASSURE™ PDA series filters combine two asymmetric polyethersulfone (PES) membrane layers with Advanced Pleat Technology design. This combination results in a robust filter that is optimised for both high throughput and fast flow applications while offering 0.2 μm absolute rated filtration for sterilising performance. The unique hydrophilic polyethersulfone membrane wets easily for integrity testing and is ideal for applications where low protein binding is critical.
