Puretratech · PT89KCSTCF
Double-layer hydrophobic PTFE capsule filter with online integrity testing, broad chemical resistance and high gas flow for critical sterile gas processes.
01 / 09
Designed for low-binding, high-value fluid filtration
This full-size capsule filter incorporates a Stäubli vent connection for online integrity testing and robust process validation.
Its double-layer hydrophobic PTFE membrane provides excellent chemical compatibility and high flow per unit area for corrosive and critical gas applications.
Every filter is integrity tested before shipment to provide reliable and repeatable out-of-package performance where stringent particle and microorganism removal is required.
