PTFE Syringe Filters, 0.22 um, 20mm, Threaded Double Luer Lock, ABS Housing, Nonsterile, 100/Pk SKU: SPEC18142

Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18142

Hydrophobic PTFE at 0.22μm gives you bacterial retention for harsh chemical environments where other membranes fail. You need to pre-wet with alcohol first, but then you get sterile filtration of aggressive solvents, concentrated acids, and corrosive organics that would destroy standard materials. This 20mm format with ABS housing handles chemical processing where both sterility and chemical resistance are non-negotiable. The 3.1cm² filtration area processes your medium-volume samples while the hydrophobic surface resists aqueous breakthrough. For pharmaceutical and chemical work demanding both microbial control and extreme chemical compatibility, you're getting PTFE's legendary durability.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophobic membrane surface requires pre-wetting with compatible organic solvents before processing aqueous solutions, ensuring proper flow initiation and sterile filtration performance
• Exceptional chemical resistance maintains integrity when exposed to aggressive laboratory chemicals, including concentrated acids, strong bases, and reactive organic solvents
• Critical 0.22µm pore architecture ensures bacterial retention while permitting efficient sterile filtration of heat-sensitive pharmaceutical compounds and chemical intermediates
• Extremely low protein binding characteristics preserve sample composition and prevent adsorptive losses during sterile processing of valuable research and pharmaceutical compounds
• Superior mechanical properties withstand high differential pressures without compromising sterile filtration performance or membrane reliability under challenging processing conditions

Key Construction Characteristics

• Robust ABS housing construction provides exceptional chemical resistance and maintains structural integrity across demanding chemical processing applications
• Compact 20mm diameter with specialized 3.1cm² filtration area reduces time by providing adequate membrane surface for sterile filtration workflows
• Threaded double luer lock design creates secure, leak-resistant connections, preventing contamination during critical sterile filtration procedures
• Reliable performance ensured through 116psi burst pressure specification provides operational confidence under demanding conditions and elevated pressures

When you need sterile filtration in chemical environments that destroy other filters, this hydrophobic PTFE membrane handles what others can't. You're processing concentrated acids, reactive solvents, and corrosive organics while still removing bacteria—that's PTFE's unique advantage. The ABS housing resists chemical attack at 116psi, so you push demanding samples through without membrane failure. Remember to pre-wet with alcohol for aqueous solutions, but once wet, you get reliable bacterial removal in the harshest chemical matrices. For pharmaceutical processing where extreme chemistry meets sterility requirements, you're getting the chemical resistance you need with 0.22μm microbial control.
