Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18155

Built with advanced 5.0µm hydrophilic-treated polytetrafluoroethylene membrane technology engineered for coarse particle removal use cases requiring exceptional chemical resistance combined with aqueous sample compatibility. Superior membrane processing eliminates the pre-wetting requirements typically associated with PTFE materials while maintaining outstanding chemical inertness essential for aggressive solvent applications. Precision manufacturing according to ISO9001 quality standards ensures reliable performance across demanding pharmaceutical, analytical, and research laboratory environments.

Key Polytetrafluoroethylene Membrane Characteristics

• Specialized hydrophilic treatment eliminates traditional PTFE pre-wetting requirements, enabling direct processing of aqueous samples and mixed media
• Exceptional chemical resistance withstands exposure to aggressive organic solvents, strong acids, caustic bases, and aromatic compounds
• Large 5.0µm pore openings provide efficient coarse filtration and protect downstream analytical equipment from damaging particulate contamination
• Extremely low protein binding maintains sample purity and prevents adsorptive losses during the filtration of valuable biological compounds
• Superior thermal stability enables processing at elevated temperatures and accommodates autoclave sterilization protocols when required

Key Construction Characteristics

• Durable polypropylene housing construction delivers broad chemical compatibility and maintains dimensional stability up to 80°C operating temperature
• Standard 25mm diameter with expansive filtration area optimizes yield by providing maximum membrane surface for efficient sample processing
• Double luer lock interface creates secure connections and prevents leakage during the processing of aggressive chemical solutions under pressure
• Robust burst pressure rating of 116psi ensures structural integrity when handling challenging samples under elevated differential pressures

Manufactured under ISO9001 certified quality standards, these specialized filters combine the chemical resistance advantages of PTFE with hydrophilic convenience for your demanding laboratory applications. Advanced membrane technology eliminates pre-wetting steps while maintaining reliable coarse filtration performance, supporting your analytical workflows with superior chemical compatibility and operational efficiency.
