PolyCap AS 75 Capsule Filter, 5/Pk SKU: 2706T

Nylon Capsule Filters - 2706T

Nylon capsule filters combine the broad chemical tolerance needed for diverse laboratory applications with the ready-to-use convenience of a self-contained, disposable filtration device. 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. Consequently, the outcome is simplified regulatory documentation and reduced contamination risk, with each single-use capsule providing a validated, traceable filtration event.

Key Nylon Membrane Characteristics

• 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.
• Non-sterile capsule delivery is appropriate for clarification, prefiltration, and general laboratory applications where the filtrate does not require sterility assurance.
• The 22 milliliter holdup volume reflects the capsule's internal fluid path geometry, relevant to recovery calculations for precious samples and small-batch pharmaceutical formulations.
• Maximum operating temperature of 60 degrees Celsius supports filtration of warm solutions and accommodates the thermal conditions present in process environments.
• 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.

Key Capsule Construction Features

• Male or female NPT fittings integrate directly with standard laboratory and industrial pipe fittings, accommodating both rigid and flexible downstream connections.
• Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
• Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
• Polypropylene capsule housing provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.

As single-use filtration continues to replace reusable housings across pharmaceutical and laboratory environments, your capsule filter selection determines both the quality of the filtrate and the efficiency of the workflow. 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. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
