Minisart® PES- Venting Filter 1757G----------Q, 0.2 µm hydrophobic PES

Minisart® PES with hydrophobic polyethersulfone (PES) is suitable for venting or filtration of gases and air. Type 1757G with a pore size of 0.2 µm can be used for sterile filtration and has a hose barb inlet and outlet. Version Q is a non-sterile bulk pack. Units can be sterilized by gamma irradiation, autoclaving or EO.

Item no.:  1757G----------Q

Availability:  On Request

Non-sterile Minisart® PES- syringe filters are supplied in bulk packs. 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.
