Polyethersulfone (PES) Capsule Filters - SF14956
PES capsule filters combine asymmetric membrane architecture with ultra-low protein adsorption, maximizing throughput while preserving the biological activity of filtered solutions. Additionally, PES membrane chemistry delivers broad pH compatibility from 1 to 14, supporting filtration of buffers, media, and cleaning solutions through a single capsule platform without material degradation. Working in concert, the outcome is simplified regulatory documentation and reduced contamination risk, with each single-use capsule providing a validated, traceable filtration event.
Key Polyethersulfone (PES) Membrane Characteristics
- PES membrane capsules deliver broad pH compatibility from 1 to 14, accommodating the full range of buffers, media, and cleaning solutions encountered in biopharmaceutical processing.
- 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.
- The 75.4 psi maximum pressure rating accommodates the differential pressures generated during filtration of particle-laden solutions as the membrane progressively loads.
- The 80 degree Celsius temperature limit ensures reliable capsule performance for ambient and moderately heated filtration applications.
- 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.
Key Capsule Construction Features
- 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 provides broad chemical compatibility from pH 1 to 14, resisting the acids, bases, and process chemicals that degrade alternative housing materials.
- Polypropylene capsule housing supports autoclave sterilization at 121 degrees Celsius and withstands gamma irradiation exposure, accommodating both user-sterilized and factory-sterilized device configurations.
- Thermally fused polypropylene construction eliminates adhesives, binders, and O-rings from the fluid path, reducing extractable contamination and simplifying material qualification.
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. To that end, if your process involves aqueous biologicals, the ultra-low protein binding and broad pH compatibility of PES membrane construction protect your product while sustaining the flow rates your batch schedule requires. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
Sterilization Guidance
Non-sterile delivery accommodates applications where sterility is not required, while the all-polypropylene construction provides the option for autoclave sterilization when aseptic processing is specified.
