Polyethersulfone (PES) Capsule Filters - 6717-9501

When processing aqueous biologicals at volumes beyond syringe filter capacity, PES capsule filters provide the throughput and recovery performance that bench-scale devices cannot match. On the performance side, asymmetric PES membrane construction captures contaminants at the upstream surface while maintaining open pore channels beneath, extending capsule service life and reducing the frequency of mid-batch device changes. The outcome is a validated filtration barrier that arrives ready for process integration, supporting the single-use manufacturing strategies adopted by modern pharmaceutical and biotechnology facilities.

Key Polyethersulfone (PES) 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 inherently hydrophilic PES membrane wets immediately on contact with aqueous solutions, eliminating alcohol pre-flush steps and reducing both startup time and solvent waste.
The 250 milliliter holdup volume reflects the capsule's internal fluid path geometry, relevant to recovery calculations for precious samples and small-batch pharmaceutical formulations.
The 121 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.
PES membrane construction supports integrity testing by forward flow, bubble point, or pressure decay methods, providing the post-use verification required by pharmaceutical quality systems.

Key Capsule Construction Features

Polypropylene housing materials provide documented biocompatibility and low extractable profiles, supporting integration into pharmaceutical and food-processing filtration applications.
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.
Stepped hose barb design accommodates multiple tubing sizes on a single fitting, simplifying inventory management and enabling connection flexibility across different process configurations.

When your filtration protocol calls for a validated, integrity-testable barrier that arrives ready to connect and begins filtering immediately, the capsule format delivers that capability without the overhead of traditional filter assemblies. When your filtration protocol demands both validated retention and maximum product recovery, PES membrane architecture balances performance with the low-adsorption surface chemistry your biologics require. 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

Factory sterilization ensures the device is ready for immediate use in aseptic applications, with validated sterility maintained through the sealed packaging until the labeled expiration date.
