Puretratech · PT89KCBRCN
Naturally hydrophilic nylon capsule filter with high specific flow and no IPA pre-wetting requirement for clean critical aqueous filtration.

01 / 09
Designed for low-binding, high-value fluid filtration
This full-size nylon capsule filter is designed for critical aqueous fluid handling in bioprocess and fine-chemical operations.
The naturally hydrophilic nylon membrane in an all-polypropylene construction provides broad chemical compatibility and high flow per unit area.
No IPA pre-wetting or DI-water flushing is required, eliminating a potential preparation-stage contamination source.
