Puretratech · PT89KCSTCV
Double-layer hydrophilic PVDF capsule filter with adhesive-free construction, high flow and low extractables for validated aqueous bioprocess filtration.
01 / 09
Designed for low-binding, high-value fluid filtration
This full-size capsule filter incorporates a Stäubli vent connection for online integrity testing in regulatory-oriented biopharmaceutical workflows.
Its double-layer hydrophilic PVDF membrane provides reliable retention, broad chemical compatibility, high flow and low extractables in aqueous process fluids.
The adhesive-, binder- and surfactant-free construction is rinsed with high-purity water to improve downstream cleanliness and reduce batch downtime.
