PTFE Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: FJ13BNPPT002AD01

Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.22um pore size in a 13mm format, this syringe filter delivers fast, reliable clarification of aqueous, organic, and alcohol-based solutions as well as gases. The membrane is welded into a transparent polypropylene housing with an 18mm housing diameter, and the unit features a Female Luer Lock inlet and a Male Luer Slip outlet for secure syringe attachment and controlled dispensing. The design maintains a low hold-up volume to preserve small or costly samples, and each filter ships nonsterile, 500 per pack.

Key PTFE Membrane Characteristics

• Naturally hydrophobic PTFE membrane ideal for filtering organic solvents, aggressive chemicals, and gases.
• Broad chemical compatibility across aqueous, organic, and alcohol solutions.
• 0.22um pore size for fine particulate removal and sample clarification.
• Low protein-binding surface that helps preserve sample integrity.
• 13mm membrane diameter suited to small sample volumes.

Key Construction Characteristics

• Transparent polypropylene housing with an 18mm housing diameter for visual monitoring of filtration.
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for versatile syringe connection.
• Ultrasonically welded construction and integrity testing help eliminate filter bypass.
• Nonsterile, packaged 500 per pack.
• Each filter is labeled with the membrane material and pore size for identification outside its original packaging.

This filter provides consistent, repeatable performance for routine sample preparation, maintaining a tight seal under pressure to prevent leakage at the seam. The low hold-up volume helps maximize recovery from limited samples, while the chemically resistant PTFE membrane supports demanding solvent applications without compromising filtrate quality.
