Polytetrafluoroethylene (PTFE) Syringe Filters - SF18275

When you're filtering aggressive solvents and need to remove fine particles from small sample volumes, these 1.0µm PTFE filters combine just 10µL holdup volume with broad chemical resistance. The hydrophobic membrane removes fine particles and suspended solids from non-aqueous solutions while handling strong acids, bases, and challenging organics. With a compact 13mm diameter, you maximize recovery of precious analytical samples. Pre-sterilized packaging means contamination-free handling, and polypropylene housing withstands pressures up to 87psi.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively filters organic solvents, acids, and bases without chemical interaction
• 1.0µm pore size removes fine particles and suspended solids from small-volume samples
• Pre-sterilized by gamma irradiation ensures contamination-free handling for critical laboratory applications
• Broad chemical resistance from strong carbon-fluorine bonds maintains stability in aggressive solvent systems
• Membrane thickness of 80-140µm optimizes retention efficiency while maintaining flow for small volumes

Key Construction Characteristics

• Polypropylene housing ensures broad chemical compatibility with organic and inorganic solvents
• Small 13mm diameter with 1.09cm² filtration area, ideal for precious samples and limited-volume applications
• Low holdup volume of 10µL maximizes recovery of expensive or irreplaceable analytical samples
• Luer-Lok/Luer Slip dual connection system accommodates various syringe sizes for versatile operation

Pre-sterilized packaging means you can start filtering immediately without autoclaving preparation, important when processing multiple analytical samples. You recover virtually all of your sample with just 10µL holdup volume - critical when working with expensive reagents or limited specimens. Process samples at temperatures up to 60°C without membrane degradation, and the 4.35psi bubble point confirms consistent 1.0µm pore structure for reproducible fine particle removal.
