Online integrity-testable hydrophilic PES capsule filter with a double-layer sterilizing-grade membrane and low protein binding for high-value biological fluids.
01 / 09
Designed for low-binding, high-value fluid filtration
This full-size capsule filter features Stäubli vent connections that facilitate in-situ integrity testing.
Its all-polypropylene construction incorporates a double-layer hydrophilic polyethersulfone (PES) membrane, providing broad chemical compatibility, high throughput at low pressure drop and low extractables.
The low protein-binding characteristics of PES make this filter well suited to high-value protein-containing solutions, including vaccines and biotherapeutics.
