Polyethersulfone membranes for aqueous solutions

AS Polydisc filters use polyethersulfone membranes, which are low protein binding and surfactant free, making them the recommended membrane for many pharmaceutical applications.

These membranes have been demonstrated to contribute low levels of extractables which might otherwise interfere with sample analysis. Polydisc AS also incorporates a glass microfiber prefilter to handle heavy particulates and extend membrane life.

Irradiation sterilized for immediate pharmaceutical use

Nonsterile filters can be sterilized in the lab by autoclaving, but filters must be tested afterwards to ensure integrity. AS Polydisc filters eliminate the need for autoclaving, because each filter is provided irradiated and presterilized in its own "medical grade" clear blister pack, secured in a protective shelf pack.
