Introducing 3M™ Emphaze AEX Hybrid Purifier!

A NEW Technology from 3M—A Single-Use Purifier for Biopharmaceutical Processes

Designed to achieve high product purity early in the manufacturing process workflow through chromatography, improving efficiency and economics.

3M™ Emphaze AEX Hybrid Purifiers - Efficiency, Purity, Economics


  • Reduces the load on chromatography columns with a single-use product
  • Purity.

  • Provides high fluid purity as early as possible in the downstream process
  • Provides the expensive protein A column the best possible protection
  • Economics.

  • Helps reduce the total cost of ownership by simplifying the process train

    For Small-Scale Sterile Air and Vent Applications

    For Small-Scale Sterile Air and Vent Applications

    LifeASSURE™ PFS Series 50 mm Capsule Filters are ideal for air filtration applications in the laboratory. Containing the same filter media as 3M's full size capsules and filter cartridges, the 50 mm devices are convenient and have low hold-up volumes.

    These products offer the ultimate in microorganism retention for air and gas streams while providing superior air flow capacity.

    LifeASSURE PFS Series PTFE Capsule Filters are validated for sterilizing performance using a liquid bacteria (B. diminuta) challenge test method.

    Small-Scale Sterilizing Grade Liquid Filtration

    Small-Scale Sterilizing Grade Liquid Filtration

    The LifeASSURE™ PDA Series 50 mm Capsule Filter combines two asymmetric polyethersulfone (PES) membrane layers in a design that is optimized for both high throughput and fast flow applications while offering 0.2 μm absolute-rated filtration for sterilizing performance. The hydrophilic polyethersulfone membrane wets easily for integrity testing and is ideal for applications where low protein binding is critical.

    The upstream layer of the capsule filter is highly asymmetric and provides optimized prefiltration capacity for the downstream layer, which contains a centrally located, retention zone.
