Whatman Polydisc AS (Aqueous Solution) in-line filters from Cytiva feature high-throughput PES membrane with a glass microfiber prefilter. Polydisc comes presterilized in medical-grade blister packs

  • Whatman filters with polyethersulfone membranes have low protein binding and are surfactant-free
  • GMF prefilter removes heavy particulates, increasing membrane longevity
  • Radiation sterilized, 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
  • Recyclable after use

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.

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.
