In industries where precision, purity, and durability are non-negotiable—from pharmaceuticals to chemical processing—the right filtration solution can make all the difference. The Nylon Capsule Filter (PN series) emerges as a standout choice, combining the unique properties of hydrophilic nylon 66 with robust engineering to deliver reliable performance in water and chemical filtration. Let’s explore why this filter is a trusted ally for critical applications.

Hydrophilic Nylon 66: The Foundation of Excellence

At the core of the PN series Nylon Capsule Filter is a hydrophilic nylon 66 membrane—a material celebrated for its dual strengths: natural wettability and exceptional resilience. Unlike hydrophobic alternatives, its inherent hydrophilicity ensures quick and easy priming, eliminating the need for pre-wetting agents and streamlining startup processes. This makes it ideal for water-based solutions, where efficient wetting is key to consistent flow.

Nylon 66 also brings impressive chemical compatibility to the table, tolerating a wide range of organic solvents and high-purity chemicals. Paired with a support structure (including drainage layers, core, cage, and shell) made from durable polypropylene (PP), the filter balances flexibility with strength, standing up to rigorous operational demands without compromising performance.

Performance That Delivers: Efficiency and Longevity

The PN series is engineered to excel in both particle removal and microbial control, making it a versatile workhorse:

Precise Filtration Ratings: With removal ratings ranging from 0.10μm to 5.0μm, it reliably captures contaminants—from fine particles to typical bacteria—verified through batch testing to reduce microbial load effectively. This precision is critical for sterile applications like API and antibiotic solution filtration.

High Flux, Low Differential Pressure: The membrane’s optimized design ensures high flow rates while maintaining low pressure drop, extending service life and reducing operational costs. Whether filtering large volumes of water or viscous chemicals, it maintains consistent performance.

Flexible Sterilization Options: Adaptable to diverse needs, it supports autoclaving (124℃ for 30min or 134℃ for 20min, up to 5 cycles) and gamma irradiation (25 kGy recommended). For sterile applications, ethylene oxide (EO) sterilization is available (with residual validation costs).

Applications: Tailored to Critical Industries

The Nylon Capsule Filter’s versatility shines across key sectors:

Pharmaceuticals: Sterile filtration of APIs, antibiotics, physiological saline, and reagent water, ensuring compliance with strict purity standards.

Chemicals: Filtration of high-purity chemicals and organic solvents, protecting downstream processes from contamination.

Biomedicals: Handling small-volume parenterals (SVP) and large-volume parenterals (LVP), where sterility and consistency are paramount.

With a range of sizes (C80, C150, C300, C605-C630) offering filtration areas from 500cm² to 19,200cm², and diverse connections (NPT, hosebarb, tri-clamp), it integrates seamlessly into any system, from small-scale labs to industrial setups.

Trust in Safety and Compliance

Safety is embedded in every detail. The filter meets USP <87> in vitro cytotoxicity standards and USP <88> Class VI-121°C plastic biological reactivity criteria, with endotoxin levels below 0.25EU/ml—critical for applications involving sensitive biological materials or injectables.
