Whatman ™ Polydisc AS (Aqueous Solution) in-line filters from Cytiva feature high-throughput PES membrane with a glass microfiber prefilter. Available irradiated or nonsterile.
Whatman filters with polyethersulfone membranes have low protein binding and are surfactant-free
GMF prefilter removes heavy particulates, increasing membrane longevity
Gamma irradiated, so there are no ethylene oxide (EtO) residuals
Barbed hose connections fit multiple tubing sizes
Integrity-testable with the bubble point method
Lightweight design prevents tubing collapse
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 applications such as buffer or reagent filtration.
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.
