Nylon Capsule Filter, 0.45um, 72mm x 95mm, 1/4 - 3/8 in. Stepped Hose Barb, Nonsterile, 1/Pk SKU: SF14922

Nylon Capsule Filters - SF14922

Nylon capsule filters combine the broad chemical tolerance needed for diverse laboratory applications with the ready-to-use convenience of a self-contained, disposable filtration device. Furthermore, nylon membrane construction in the pleated capsule format delivers the effective filtration area needed for large-volume reagent preparation while maintaining the chemical versatility that defines this material. By design, the outcome is simplified regulatory documentation and reduced contamination risk, with each single-use capsule providing a validated, traceable filtration event.

Key Nylon Membrane Characteristics

• 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.
• Nylon capsule filters resist common laboratory solvents including alcohols, esters, and bases, while maintaining stable performance above pH 3 across typical processing conditions.
• Rated for operating pressures up to 75.4 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.
• The 25 milliliter holdup volume reflects the capsule's internal fluid path geometry, relevant to recovery calculations for precious samples and small-batch pharmaceutical formulations.
• Single-layer membrane construction provides direct, absolute retention at the rated pore size without the additional flow resistance introduced by upstream prefilter layers.

Key Capsule Construction Features

• 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 capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
• 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.

When your filtration protocol calls for a validated, integrity-testable barrier that arrives ready to connect and begins filtering immediately, the capsule format delivers that capability without the overhead of traditional filter assemblies. For facilities processing buffers, reagents, and mixed solvent systems, nylon capsule filters provide the chemical versatility your multi-application laboratory environment demands. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Non-sterile delivery accommodates applications where sterility is not required, while the all-polypropylene construction provides the option for autoclave sterilization when aseptic processing is specified.
