Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC16279

Addressing persistent challenges in aggressive solvent prefiltration and protecting valuable downstream equipment, these specialized 3.0µm polytetrafluoroethylene membrane filters provide reliable solutions for removing coarse particles from harsh chemical environments. Advanced hydrophobic membrane technology delivers consistent prefiltration performance while maintaining integrity under chemical exposure that would degrade alternative membrane materials. Enhanced technical specifications ensure dependable operation throughout demanding pharmaceutical manufacturing and analytical laboratory processing applications.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane surface requires pre-wetting with appropriate organic solvents before processing aqueous solutions, ensuring optimal flow characteristics and performance
• Outstanding chemical resistance maintains stability when exposed to aggressive laboratory solvents, including strong acids, caustic bases, and reactive organic compounds
• Strategic 3.0µm pore configuration efficiently captures coarse contaminants while permitting rapid throughput for efficient prefiltration of challenging sample matrices
• Extremely low protein binding preserves sample composition and prevents fouling during processing of complex biological and pharmaceutical formulations
• Superior thermal resilience enables autoclave sterilization at 121°C and processing at elevated temperatures up to 80°C operating conditions

Key Construction Characteristics

• Lightweight polypropylene housing construction provides broad chemical compatibility and maintains structural integrity across temperature variations
• Standard 25mm diameter with expansive 4.9cm² filtration area preserves samples by maximizing membrane surface for efficient coarse particle removal
• Double luer lock interface ensures secure connections and prevents leakage during high-pressure processing of organic solvents and chemical solutions
• Operational confidence provided by 116psi burst pressure rating ensures reliable performance under demanding laboratory conditions and elevated pressures

Designed to overcome your most challenging prefiltration obstacles, these precision filters provide reliable coarse particle removal while maintaining chemical resistance under harsh operating conditions. Advanced polytetrafluoroethylene membrane technology ensures consistent prefiltration results and dependable operation, supporting your laboratory workflows with superior chemical compatibility and protective equipment performance.
