Double-layer naturally hydrophilic nylon capsule filter for dependable retention, high flow and contamination-controlled aqueous processing.
01 / 09
Designed for low-binding, high-value fluid filtration
This full-size capsule filter is engineered for biopharmaceutical and fine-chemical aqueous filtration workflows.
Its double-layer nylon membrane in an all-polypropylene construction provides broad chemical compatibility, high specific flow and dependable particle retention.
The naturally hydrophilic membrane requires neither IPA pre-wetting nor DI-water flushing, reducing pretreatment-related contamination risk.
