Individually packed and sterile Minisart® High Flow syringe filters are optimal for immediate usage whenever sterile filtration or clarification and cell removal under sterile conditions is needed. 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 the acrylic resin MBS (Methacrylate butadiene styrene) which has a limited compatibility with alcohols but is free of phthalates and passes the plastic class VI test.
