Minisart® PES with polyethersulfone (PES) is optimal for highest flow rates and a pH of 2 - 13. Type 1776D with a pore size of 0.22 µm can be used for sterile filtration and has a male luer slip outlet. Version ACK is individually packed and sterilized by ethylene oxide (EO).

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.
