Polytetrafluoroethylene (PTFE) Syringe Filters - SPEC18163

When you're filtering aqueous samples and need PTFE's chemical resistance without the pre-wetting hassle, these hydrophilic-treated filters solve that problem. The 5.0µm pore size removes coarse particles and debris from biological solutions while the surface treatment lets you process water-based samples immediately. The 20mm diameter with 3.14cm² filtration area handles small to medium sample volumes efficiently, and ABS housing provides chemical compatibility with both aqueous and organic solutions.

Key Polytetrafluoroethylene Membrane Characteristics

• Hydrophilic surface treatment eliminates pre-wetting requirements for immediate aqueous sample processing
• 5.0µm pore size removes coarse particles and debris while maintaining rapid flow rates
• Low protein binding minimizes sample loss when filtering biological solutions
• Broad chemical compatibility handles both aqueous solutions and organic solvents
• Membrane thickness of 80-140µm provides structural stability during high-pressure filtration

Key Construction Characteristics

• ABS housing provides chemical resistance across diverse laboratory applications
• 20mm diameter with 3.14cm² filtration area for efficient small to medium-volume processing
• Threaded double luer lock design ensures secure connections during sample processing
• 116psi burst pressure provides reliable performance under elevated pressure conditions

You can autoclave these filters at 121°C for 30 minutes when your protocols require sterilization before use. The hydrophilic treatment means you process aqueous samples immediately without alcohol pre-wetting - saving preparation time when running multiple samples. The coarse 5.0µm pore structure handles particulate-laden samples that would quickly clog finer membranes, extending filter life when processing biological solutions with cellular debris or precipitates.
