Polysulfone microporous membrane filter

Product Features

· Material
　　polysulfone (Suporfone) is by far the most ideal high-porosity microporous filter membrane, with natural hydrophilicity, using polypropylene inner core, end cover, outer cover. With polypropylene as the support layer, the materials used comply with GMP and FDA requirements, do not use surfactants, and have broad chemical compatibility with wetting agents.
· The structural
　　filter element is a composite filter element which is folded with hydrophilic polysulfone Supor membrane and polypropylene. It has high porosity and high flow rate. It adopts hot-melt sealing technology, does not use any additives and adhesives, and has no unloading and medium. migrate.

Filtration accuracy

　　Absolute accuracy: 0.2um, 0.45um, 0.65um

Operating conditions

·Maximum operating pressure difference 5.5bar at 20℃ ·Maximum operating pressure difference 5.3bar at 50℃ ·Maximum operating pressure difference 4.1bar
at 80℃
·Maximum continuous use temperature 80℃
·Steam maximum sterilization temperature 140℃, cumulative Time 72 hours.

advantage

·The outer polypropylene layer plays a pre-filtering role, protecting the polysulfone membrane from being blocked.
· Extensive chemical resistance and stability.
·Good hydrophilicity, large flow, no need to wet in advance.
· Perform integrity testing before leaving the factory to ensure the sterilization effect.
·Small adsorption, ensuring high purity of the filtrate.
