Polypropylene Capsule Filter, 3.0um, 72mm x 95mm, 1/4 - 3/8 in. Step Hose Barb, Nonsterile, 1/Pk SKU: SF14945

Polypropylene (PP) Capsule Filters - SF14945

Polypropylene capsule filters address industrial and laboratory clarification needs where chemical resistance, autoclavability, and cost-effective disposability are primary requirements. Central to its design, 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. Taken together, 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 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.
• Maximum operating pressure of 75.4 psi provides the differential pressure capacity needed for sustained filtration of viscous solutions and high-flow process streams.
• Non-sterile capsules support autoclave sterilization where the membrane and housing materials permit, allowing users to prepare devices according to their own validated sterilization protocols.
• The single membrane configuration is appropriate for pre-clarified feed streams where upstream particulate removal has already reduced the contaminant load to levels within the capsule's dirt-holding capacity.
• 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.

Key Capsule Construction Features

• Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
• Single-use polypropylene capsule construction eliminates cleaning validation requirements, reducing the regulatory burden and turnaround time associated with reusable stainless steel filter housings.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.

Whether your process requires sterilizing-grade retention for a 500-milliliter bench trial or clarification capacity for a 100-liter production batch, the right capsule filter configuration eliminates the compromises between throughput, retention, and operational simplicity. For applications like these, 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. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

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.
