The LifeTec™ PES-WN filter element provides the greatest assurance of filtration performance, stability and service life for sterile filtration and microbial stabilization.
  LifeTec PES-WN Filter Element

The outstanding performance of the PES-WN filter element is based on its state-of-the-art filtration media. The hydrophilic polyethersulfone membrane distinguishes itself by having an asymmetrically designed pore structure.

The pore size steadily decreases towards the center 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 contaminants.
