Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18136

Addressing the persistent challenge of processing aggressive solvents and corrosive media in laboratory environments, these specialized 5.0µm polytetrafluoroethylene membrane filters provide reliable solutions for coarse particle removal and equipment protection. Advanced hydrophobic membrane technology delivers consistent prefiltration performance while withstanding chemical exposure that would degrade conventional filter materials. Enhanced 25mm diameter construction with polypropylene housing ensures dependable operation throughout demanding pharmaceutical and chemical processing applications.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane surface requires pre-wetting with compatible organic solvents before processing aqueous samples, ensuring proper flow initiation and performance
• Exceptional chemical resistance maintains integrity when exposed to the most aggressive laboratory chemicals, including strong acids, caustic bases, and organic solvents
• Strategic 5.0µm pore configuration captures coarse particles and debris while permitting rapid flow rates through viscous and challenging sample matrices
• Extremely low protein binding characteristics preserve sample purity and minimize adsorptive losses during the filtration of valuable research compounds
• Outstanding thermal stability accommodates autoclave sterilization at 121°C and enables processing at elevated temperatures up to 80°C

Key Construction Characteristics

• Lightweight polypropylene housing construction provides broad chemical compatibility and maintains dimensional stability across varying temperature conditions
• Standard 25mm diameter with expanded 4.9cm² filtration area preserves samples by maximizing membrane surface for efficient coarse filtration
• Double luer lock connection system ensures secure attachment and prevents leakage during high-pressure processing of aggressive chemical solutions
• Robust burst pressure capacity of 116psi provides structural integrity for demanding applications involving elevated pressures and viscous samples

Built to overcome your most challenging chemical filtration obstacles, these precision filters deliver reliable coarse filtration performance while maintaining membrane integrity under harsh operating conditions. Advanced polytetrafluoroethylene membrane technology ensures consistent particle removal and dependable operation, supporting your laboratory workflows with superior chemical resistance and reliable filtration efficiency.
