PolyCap AS 36 Capsule Filter SKU: 6706-3602

Nylon Capsule Filters - 6706-3602

From reagent preparation to environmental sample processing, nylon capsule filters provide the versatility required for multi-solvent filtration workflows at bench and pilot scale. Naturally hydrophilic nylon membrane within the capsule housing wets immediately on contact with aqueous solutions, eliminating pre-conditioning steps and enabling rapid filtration startup for time-sensitive applications. 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

• The prefilter-final filter combination within a single capsule housing provides graduated retention that extends device life when processing biological fluids with variable particulate loads.
• The broad solvent compatibility of nylon membranes extends across aqueous, alcoholic, and many organic systems, providing a versatile capsule platform for laboratories processing diverse reagent types.
• Nylon capsule filters provide a cost-effective filtration option for high-volume reagent preparation, buffer filtration, and general laboratory applications where ultra-low binding is not the primary requirement.
• 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.
• 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.

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.
• 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.
• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.

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. If your laboratory processes diverse aqueous and organic solutions, the natural hydrophilicity and broad solvent compatibility of nylon membrane construction simplifies your workflow across application types. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Sterilization Guidance
