Excellent chemical resistance, efficiently filters fluids with high surface tension.
The LeSiever® hydrophilic PTFE filter uses biaxially oriented polytetrafluoroethylene (PTFE) as the core membrane. Through hydrophilic modification, it maintains stable filtration performance and long service life in harsh chemical environments such as strong acids, strong alkalis, and organic solvents. Its unique low protein binding and low extractable characteristics make it an ideal choice for processing highly corrosive fluids and liquids with high surface tension. This series of sterilizing-grade filters is specifically developed for aseptic filtration processes. Products at all levels, from pre-filtration to sterile filtration, comply with current regulations and industry standards. Each filter is subjected to rigorous testing before leaving the factory and is released only upon passing.
