Polypropylene Capsule Filter, 1.0um, 72mm x 111mm, 1/2 in. Hose Barb, Nonsterile, 1/Pk SKU: SF14962

Polypropylene (PP) Capsule Filters - SF14962

All-polypropylene capsule construction offers uniform chemical compatibility from membrane to housing, eliminating the material mismatch concerns that arise with multi-material filter assemblies. Manufactured to exacting specifications, all-polypropylene construction from membrane to housing provides uniform chemical resistance, eliminating the compatibility concerns that arise when membrane and housing materials respond differently to aggressive process fluids. Ultimately, the outcome is a validated filtration barrier that arrives ready for process integration, supporting the single-use manufacturing strategies adopted by modern pharmaceutical and biotechnology facilities.

Key Polypropylene (PP) Membrane Characteristics

• Polypropylene capsule construction tolerates repeated autoclave sterilization cycles at 121 degrees Celsius, supporting reuse protocols where single-use disposability is not required.
• 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.
• Internal holdup volume of 25 milliliters minimizes sample loss during capsule filtration, a critical consideration when processing expensive biologics or limited-volume preparations.
• 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.

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 housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• 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.

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. If your process generates high particulate loads or involves chemically aggressive fluids, polypropylene capsule construction provides the chemical breadth and dirt-holding capacity your clarification step requires. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Sterilization Guidance

Supplied non-sterile, the polypropylene housing supports autoclave sterilization at 121 degrees Celsius for 20 minutes when aseptic filtration is required by the application protocol.
