Whatman Polydisc In-Line Filters, Aqueous Solution

Description

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

Whatman disc filters from GE Healthcare’s Life Sciences business offer a wide range of high-throughput, in-line options.

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.
