Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18140

Addressing challenges in aggressive solvent prefiltration and coarse particle removal, these specialized 3.0µm polytetrafluoroethylene membrane filters deliver reliable solutions for protecting downstream analytical equipment and expensive fine filters. Advanced hydrophobic membrane technology combines exceptional chemical resistance with efficient flow characteristics essential for processing viscous organic solvents and corrosive media. Gamma-sterilized polypropylene housing construction ensures contamination-free sample handling while maintaining superior chemical compatibility.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane nature requires pre-wetting with appropriate organic solvents before processing aqueous solutions or mixed media
• Exceptional chemical inertness resists degradation from the most aggressive laboratory solvents, including strong acids, bases, and organic chemicals
• Large 3.0µm pore openings provide efficient coarse filtration while protecting downstream equipment from damaging particulate contamination
• Extremely low protein binding characteristics maintain sample purity and prevent adsorptive losses of valuable analytical compounds
• Outstanding thermal resilience enables processing at elevated temperatures and withstands autoclave sterilization protocols at 121°C

Key Construction Characteristics

• Lightweight polypropylene housing delivers broad chemical compatibility and maintains structural stability across temperature ranges up to 80°C
• Standard 25mm diameter with expanded 4.9cm² filtration area optimizes yield by providing maximum membrane surface for efficient processing
• Double luer lock interface creates leak-proof connections essential for containing aggressive solvents during high-pressure filtration operations
• Reliable performance up to 116psi burst pressure ensures structural integrity when processing challenging samples under elevated pressures

Built to handle your most demanding chemical filtration challenges, these gamma-sterilized filters provide reliable prefiltration performance while resisting chemical attack from aggressive media. Advanced polytetrafluoroethylene membrane technology ensures consistent particle removal and flow rates, protecting your valuable analytical systems and maintaining reliable laboratory operations.
