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 Q is a non-sterile bulk pack. Units can be sterilized by autoclaving or EO.

Non-sterile Minisart® PES syringe filters are supplied in bulk packs. This reduces waste and makes the handling easier whenever the application allows clarification and cell removal under non-sterile conditions. In addition the non-sterile filters can be assembled and sterilised by the user. 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.
