Nylon Capsule Filters - SF14988

Nylon capsule filters offer inherent hydrophilicity and broad solvent compatibility, addressing filtration needs that span aqueous solutions, alcohols, and mixed solvent systems. 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. Taken together, 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

• 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.
• 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 continuous operation at temperatures up to 80 degrees Celsius, the capsule maintains structural integrity and retention performance across the normal process temperature range.
• 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.
• 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.

Key Capsule Construction Features

• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
• 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.

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. Here, 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.
