Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC16251

Featuring advanced 0.22µm polytetrafluoroethylene membrane technology specifically engineered for aggressive chemical applications requiring sterile filtration and superior chemical resistance. Exceptional membrane performance delivers reliable bacterial elimination while withstanding harsh organic solvents, acids, and alkaline solutions that degrade conventional filter materials. Robust 25mm diameter construction with lightweight polypropylene housing provides enhanced filtration capacity for processing larger sample volumes up to 100ml.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane surface requires pre-wetting with compatible solvents before processing aqueous samples, ensuring proper flow initiation
• Outstanding chemical resistance maintains integrity when exposed to aggressive organic solvents, strong acids, and caustic solutions
• Critical 0.22µm pore structure provides absolute bacterial retention while permitting efficient sterile filtration of pharmaceutical compounds
• Extremely low protein binding preserves valuable biomolecules and prevents adsorptive losses during the filtration of sensitive biological samples
• Exceptional thermal stability enables autoclave sterilization at 121°C and gamma sterilization protocols for contamination-free processing

Key Construction Characteristics

• Lightweight polypropylene housing construction delivers chemical compatibility and thermal resistance up to 80°C operating temperature
• Standard 25mm diameter with 4.9cm² filtration area maximizes recovery by providing an expanded membrane surface for efficient sample processing
• Double luer lock connection system ensures secure attachment and prevents leakage during high-pressure organic solvent filtration
• Burst pressure capability of 116psi provides structural integrity for demanding applications involving viscous solvents and elevated pressures

Engineered to excel in your most challenging chemical filtration applications, these versatile filters provide dependable sterile filtration performance while resisting degradation from aggressive solvents and corrosive media. Advanced polytetrafluoroethylene membrane technology ensures reliable bacterial removal while maintaining your critical sample integrity throughout demanding laboratory processes.
