Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18152

Built with precision 0.22µm hydrophilic-treated polytetrafluoroethylene membrane technology engineered for critical sterile filtration use cases requiring exceptional chemical resistance combined with aqueous sample compatibility. Advanced membrane processing eliminates traditional PTFE pre-wetting requirements while delivering absolute bacterial retention essential for pharmaceutical manufacturing and biotechnology applications. Superior construction utilizing ISO-grade manufacturing quality standards ensures reliable microbial elimination throughout demanding laboratory and production environments.

Key Polytetrafluoroethylene Membrane Characteristics

• Specialized hydrophilic treatment eliminates pre-wetting requirements, enabling direct processing of aqueous samples, biological media, and mixed solvent systems
• Outstanding chemical inertness maintains integrity when exposed to aggressive pharmaceutical solvents, strong acids, caustic bases, and organic aromatics
• Critical 0.22µm pore architecture ensures absolute bacterial retention while permitting efficient sterile filtration of heat-sensitive pharmaceutical compounds
• Extremely low protein binding maintains biomolecule integrity and prevents adsorptive losses during sterile processing of valuable biological preparations
• Superior mechanical durability withstands high differential pressures without compromising sterile filtration performance or membrane reliability

Key Construction Characteristics

• Lightweight polypropylene housing construction delivers broad chemical compatibility and maintains dimensional stability across temperature ranges up to 80°C
• Standard 25mm diameter with expansive 4.9cm² filtration area optimizes yield by providing maximum membrane surface for sterile processing applications
• Double luer lock interface creates secure, leak-resistant connections, preventing microbial contamination during critical sterile filtration procedures
• Robust burst pressure rating of 116psi ensures structural integrity for demanding applications involving elevated pressures and challenging sample matrices

Engineered to deliver your most demanding sterile filtration requirements, these specialty filters combine the chemical resistance advantages of PTFE with hydrophilic processing convenience for critical applications. Advanced membrane technology eliminates pre-wetting complications while maintaining reliable bacterial elimination, supporting your sterile processing objectives with superior chemical compatibility and operational simplicity.
