Minisart® PES with hydrophobic polyethersulfone (PES) is suitable for venting or filtration of gases and air.

• Non-sterile filters for assembly
• High chemical compatibility
• Suitable as venting filter

Units can be sterilized by gamma irradiation, autoclaving or EO. Non-sterile Minisart® PES- syringe filters are supplied in a pouch in one pack. This reduces waste and makes the handling easier whenever the application allows venting under non-sterile conditions.

In addition the non-sterile filters can be assembled and sterilised by the user. The hydrophobic PES membrane functions as a water barrier and does not become wetted by aerosols. This keeps the hydrophobic venting filter permeable for gas or air. The housing of the filter is made of gamma-sterilisable PP (polypropylene) which is compatibility with harsh gases.
