Polypropylene Capsule Filter, 5.0um, 72mm x 95mm, 1/4 - 3/8 in. Step Hose Barb, Nonsterile, 1/Pk SKU: SF14946

Polypropylene (PP) Capsule Filters - SF14946

For high-particulate or chemically aggressive fluid streams, polypropylene capsule filters provide the loading capacity and chemical resistance needed for reliable in-line operation. Equally important, polypropylene capsule construction withstands repeated autoclave sterilization cycles, supporting reuse protocols in applications where single-use economics are not favorable. Because of this, the result is a filtration workflow that scales efficiently from method development through production, delivering consistent retention performance across the full range of capsule effective filtration areas.

Key Polypropylene (PP) Membrane Characteristics

• The depth-type polypropylene media provides high dirt-holding capacity for prefiltration and clarification, extending the service life of downstream sterilizing-grade membrane filters.
• Polypropylene capsule filters serve as effective guard filters upstream of sensitive analytical instruments and sterilizing-grade membrane devices, removing gross particulates that would cause premature fouling.
• 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.
• All-polypropylene capsule construction ensures that membrane, support layers, and housing share identical chemical resistance, eliminating compatibility mismatches across the device.
• The hydrophobic polypropylene matrix provides effective filtration of organic solvents and non-aqueous process fluids without the pre-wetting steps required for aqueous applications.

Key Capsule Construction Features

• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• 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. When your application requires chemical resistance across the full pH range combined with the ability to withstand autoclave sterilization, all-polypropylene construction meets your combined durability requirements. 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.
