Polypropylene Capsule Filter, 0.45um, 72mm x 95mm, 1/4 - 3/8 in. Stepped Hose Barb, Nonsterile, 1/Pk SKU: SF14968

Polypropylene (PP) Capsule Filters - SF14968

Polypropylene capsule filters provide aggressive chemical resistance across the full pH range, handling strong acids, bases, and organic solvents that attack other membrane materials. Built for consistent results, the depth-style polypropylene media within the capsule housing provides high dirt-holding capacity for clarification and prefiltration applications where particulate loads would rapidly foul membrane-based devices. Accordingly, 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 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.
• Polypropylene capsule filters withstand aggressive chemical environments across the full pH range, from concentrated acids to strong bases, without membrane degradation or extractable release.
• The hydrophobic polypropylene matrix provides effective filtration of organic solvents and non-aqueous process fluids without the pre-wetting steps required for aqueous applications.
• 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.
• Capsule holdup volume of 25 milliliters represents the fluid retained within the device after filtration, an important factor when calculating yield for high-value pharmaceutical products.

Key Capsule Construction Features

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

From method development through scale-up to production, your capsule filter choice defines the balance between membrane performance, process integration, and the regulatory documentation trail that supports each filtration event. Specifically, 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

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.
