PolyCap AS 36 Capsule Filter, Sterile, 0.2um, MNPT Inlet & SB Outlet - 1pc SKU: 6709-3602

Nylon Capsule Filters - 6709-3602

From reagent preparation to environmental sample processing, nylon capsule filters provide the versatility required for multi-solvent filtration workflows at bench and pilot scale. Engineered for demanding applications, the broad solvent compatibility of nylon membrane extends across aqueous, alcoholic, and mixed organic systems, providing a single capsule platform for laboratories filtering diverse reagent types at volume. As designed, 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 Nylon Membrane Characteristics

• Maximum operating pressure of 60 psi provides the differential pressure capacity needed for sustained filtration of viscous solutions and high-flow process streams.
• The factory-sterilized device arrives with documented sterility assurance, reducing the validation burden associated with user-performed sterilization of reusable filter assemblies.
• Capsule holdup volume of 10 milliliters represents the fluid retained within the device after filtration, an important factor when calculating yield for high-value pharmaceutical products.
• 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.
• Integrated prefiltration within the capsule distributes particle loading across two membrane layers, preventing the rapid fouling that occurs when high-particulate feeds contact a single sterilizing-grade membrane.

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.
• Stepped hose barb design accommodates multiple tubing sizes on a single fitting, simplifying inventory management and enabling connection flexibility across different process configurations.
• NPT threaded capsule connections support installation in fixed piping systems where the capsule serves as a permanent or semi-permanent in-line filtration point.

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. For applications like these, for facilities processing buffers, reagents, and mixed solvent systems, nylon capsule filters provide the chemical versatility your multi-application laboratory environment demands. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
