PolyCap AS 75 Capsule Filter, 5/Pk SKU: 2707NS

Nylon Capsule Filters - 2707NS

Nylon capsule filters offer inherent hydrophilicity and broad solvent compatibility, addressing filtration needs that span aqueous solutions, alcohols, and mixed solvent systems. The broad solvent compatibility of nylon membrane extends across aqueous, alcoholic, and mixed organic systems, providing a single capsule platform for laboratories filtering diverse reagent types at volume. For this reason, the outcome is a validated filtration barrier that arrives ready for process integration, supporting the single-use manufacturing strategies adopted by modern pharmaceutical and biotechnology facilities.

Key Nylon Membrane Characteristics

• Rated for operating pressures up to 60 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.
• Non-sterile configuration accommodates laboratory and industrial applications where the capsule filter serves a clarification or protection function rather than a sterilizing-grade barrier role.
• Nylon membrane capsules offer natural hydrophilicity across their full pore structure, ensuring complete wetting with aqueous solutions without the pre-treatment steps required by hydrophobic alternatives.
• Nylon capsule filters provide a cost-effective filtration option for high-volume reagent preparation, buffer filtration, and general laboratory applications where ultra-low binding is not the primary requirement.
• The mechanical strength of nylon membrane construction supports the operating pressures encountered in capsule filtration systems without the deformation risks associated with thinner membrane materials.

Key Capsule Construction Features

• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.

From method development through scale-up to production, your capsule filter choice defines the balance between membrane performance, process integration, and the regulatory documentation trail that supports each filtration event. For applications like these, if your laboratory processes diverse aqueous and organic solutions, the natural hydrophilicity and broad solvent compatibility of nylon membrane construction simplifies your workflow across application types. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Sterilization Guidance

Supplied non-sterile, the polypropylene housing supports autoclave sterilization at 121 degrees Celsius for 20 minutes when aseptic filtration is required by the application protocol.
