Polyethersulfone (PES) Syringe Filters - SF14499

Featuring advanced polyethersulfone membrane technology engineered for critical sterile filtration applications. Laboratory professionals rely on PES membranes for exceptional bacteria removal capabilities with minimal protein binding in biological solutions. Tisch Scientific combines robust polypropylene housing construction with precision 0.22µm membrane pore size to deliver consistent sterilizing-grade filtration performance across pharmaceutical, biotechnology, and research applications.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane eliminates pre-wetting requirements for aqueous solutions
• Ultra-low protein binding preserving sample integrity in biological applications
• Sterilizing-grade 0.22µm pore size, ensuring complete bacteria removal
• Membrane thickness of 100-160µm, providing structural stability during filtration
• Broad pH compatibility supporting diverse chemical environments

Key Construction Characteristics

• Durable polypropylene housing withstanding 87psi maximum operating pressure
• Integrated PP prefilter extending primary membrane lifespan and improving throughput
• Holdup volume of 100µL, minimizing sample loss in valuable applications
• Universal Luer-Lok/Luer Slip connectivity ensures compatibility with standard syringes

SF14499 syringe filters maintain reliable flow rates of 24ml through a 4.08cm² active filtration area, optimizing your workflow efficiency while ensuring complete bacterial retention. A bubble point specification of 43.51psi validates membrane integrity for critical sterile filtration processes requiring documented performance. Autoclave sterilization at 121°C for 30 minutes or gamma irradiation protocols provide flexible sterilization options to meet your laboratory's specific requirements while maintaining operational temperatures up to 60°C.
