Nylon Capsule Filter, 0.45um, 72mm x 115mm, 1/4 in. MNPT, Nonsterile, 1/Pk SKU: SF14913

Nylon Capsule Filters - SF14913

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. On the performance side, 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. The result is a streamlined filtration step that integrates directly into fluid transfer systems, reducing hold times and minimizing the manual handling that compromises sterility assurance.

Key Nylon Membrane Characteristics

The non-sterile format provides the same membrane retention and flow performance as sterile variants, with the flexibility for user-controlled sterilization when process requirements dictate.
Rated for continuous operation at temperatures up to 80 degrees Celsius, the capsule maintains structural integrity and retention performance across the normal process temperature range.
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.
Internal holdup volume of 60 milliliters minimizes sample loss during capsule filtration, a critical consideration when processing expensive biologics or limited-volume preparations.
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

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.
Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.

As single-use filtration continues to replace reusable housings across pharmaceutical and laboratory environments, your capsule filter selection determines both the quality of the filtrate and the efficiency of the workflow. In these cases, 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. 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

Polypropylene construction throughout the device permits autoclave sterilization at standard conditions, enabling end-user preparation for sterile filtration applications as needed.
