Minisart® High Flow with polyethersulfone (PES) is optimal for highest flow rates and a pH of 3 - 12. Type 16541 with a pore size of 0.22 µm can be used for sterile filtration and has a male luer slip outlet. Version Q is a non-sterile bulk pack. Units can be sterilized by gamma irradiation or EO.

Non-sterile Minisart® High Flow syringe filters are supplied in bulk packs. This reduces waste and makes the handling easier whenever the applications allows the removal of particles or cells under non-sterile conditions. 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. It is glueable, e.g. to tubing, what enables assembly and sterilization by the user. The low binding membrane is tightly connected with the housing which allows bidirectional use. Due to the slightly asymmetric membrane structure, the PES surface almost behaves like a pre-filter and enables highest flow rates.
