Nylon Capsule Filter, 5.0um, 72mm x 115mm, 1/4 in. MNPT, Nonsterile, 1/Pk SKU: SF14917

Nylon Capsule Filters - SF14917

The naturally hydrophilic structure of nylon capsule filters eliminates pre-wetting requirements, enabling immediate use with aqueous solutions while maintaining compatibility with most organic solvents. Manufactured to exacting specifications, naturally hydrophilic nylon membrane within the capsule housing wets immediately on contact with aqueous solutions, eliminating pre-conditioning steps and enabling rapid filtration startup for time-sensitive applications. Together, the outcome is higher operational throughput with lower contamination risk, as disposable capsule devices remove the reprocessing steps that introduce variability into reusable filter systems.

Key Nylon Membrane Characteristics

Nylon membrane capsules deliver consistent retention performance across the pore size range from 0.2 to 0.45 micrometers, covering both sterilizing-grade and general clarification applications.
Non-sterile capsules support autoclave sterilization where the membrane and housing materials permit, allowing users to prepare devices according to their own validated sterilization protocols.
The 80 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.
Single-membrane construction simplifies integrity test interpretation, as the bubble point and diffusion flow values correspond directly to the rated retention membrane without prefilter interference.
The broad solvent compatibility of nylon membranes extends across aqueous, alcoholic, and many organic systems, providing a versatile capsule platform for laboratories processing diverse reagent types.

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.
The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
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 this purpose, when your filtration needs span aqueous solutions, alcohols, and organic mixtures, nylon membrane construction eliminates the pre-wetting steps and material compatibility checks that slow your workflow. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Sterilization Guidance

Standard autoclave cycles at 121 degrees Celsius are compatible with the polypropylene housing and membrane assembly, allowing preparation for sterile applications at the point of use.
