PolyCap AS 36 Capsule Filter SKU: 6705-3602

Nylon Capsule Filters - 6705-3602

Nylon capsule filters offer inherent hydrophilicity and broad solvent compatibility, addressing filtration needs that span aqueous solutions, alcohols, and mixed solvent systems. Designed for laboratory performance, 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

• Maximum operating temperature of 60 degrees Celsius supports filtration of warm solutions and accommodates the thermal conditions present in process environments.
• Nylon capsule filters resist common laboratory solvents including alcohols, esters, and bases, while maintaining stable performance above pH 3 across typical processing conditions.
• Nylon membrane capsules offer natural hydrophilicity across their full pore structure, ensuring complete wetting with aqueous solutions without the pre-treatment steps required by hydrophobic alternatives.
• 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.
• Rated for operating pressures up to 60 psi, the capsule housing withstands the system pressures encountered in peristaltic pump, pressure vessel, and gravity-feed filtration configurations.

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.
• The sealed polypropylene housing is individually integrity-tested during manufacturing, verifying membrane installation and housing seal quality before the device leaves the production facility.
• Barbed inlet and outlet connections provide a practical, leak-resistant interface for gravity-feed, peristaltic pump, and pressure-driven filtration systems using flexible tubing.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.

As batch volumes and regulatory expectations continue to grow, your capsule filter selection becomes a process design decision that affects sterility assurance, product recovery, and operational cost per liter filtered. For this purpose, 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.
