Millipore Millipak Express 20 Filter 0.22 um Durapore

The Millipore MPGP02001 Millipak Express 20 is a high-performance, point-of-use membrane filter designed to provide particulate-free and bacteria-free water for critical laboratory applications. Engineered specifically for use with Millipore water purification systems, this filter utilizes a 0.22 micron hydrophilic membrane to ensure the highest level of water purity at the point of dispense. Its unique stacked-disc design provides a safe and efficient barrier against contaminants while maintaining optimal flow rates.

Technical Performance and Design

• High-Flow Asymmetric Membrane: Features a 0.22 micron polyethersulfone (PES) membrane with conical pores that allow for high flow rates at low differential pressures.

• Stacked-Disc Technology: Utilizes a clean stacked-disc design that eliminates the risk of particulate-producing woven downstream supports often found in pleated membrane capsules.

• Low Extractables: The membrane is heat-sealed to a styrene acrylonitrile (SAN) housing, minimizing the release of organic and inorganic extractables and ensuring a high-purity fluid path.

• Integrated Protective Bell: Equipped with a protective bell at the outlet to shield the dispense point from airborne bacterial contamination during use.
