Minisart® PES with polyethersulfone (PES) is optimal for highest flow rates and a pH of 2 to 13.

• Low adsorption of analytes
• Maximum chemical compatibility
• Minimum extractables or leachable
• Bidirectional use possible
• 100% optical integrity test

Due to the slightly asymmetric membrane structure, the PES surface almost behaves like a pre-filter and enables highest flow rates. The low binding membrane is tightly connected with the housing which allows bidirectional use. The housing is made of polypropylene, which is compatibility with harsh solvents, acids and bases.
