The LifeTec PES-WN filter element is a sterile grade, pleated high performance Polyethersulfone membrane filter. It provides the greatest assurance of filtration performance, stability and service life for sterile filtration and microbial
stabilization. The outstanding performance of the LifeTec PES-WN filter
element is based on its state-of-the-art filtration media. The Polyethersulfone membrane is inherently hydrophilic and distinguishes itself by having an asymmetrically designed pore structure. The pore size steadily decreases towards the centre of the medium resulting in a highly porous structure.
This extremely durable design maintains consistent porosity and impurity retention throughout its service life without shedding or unloading contaminations.
