Individually packed and sterile Minisart® PES 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 PP (polypropylene) which is compatibility with harsh solvents, acids and bases. Sterile and ready-to-use Slightly asymmetric PES with superior flow rate Low non-specific binding Bidirectional use possible
