PTFE Hydrophilic Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: FJ25BNPPH004AD01

Featuring a naturally wettable hydrophilic polytetrafluoroethylene (PTFE) membrane with a 0.45um pore size, these 25mm syringe filters deliver rapid clarification of aqueous, alcoholic, and organic solutions prior to analysis. The 0.45um membrane removes particulates that can clog columns and obscure results, while the broadly inert PTFE chemistry maintains compatibility across a wide range of solvents. The transparent polypropylene housing is ultrasonically welded for integrity and provides bidirectional membrane support for either injection or aspiration.

Key PTFE Membrane Characteristics

• Hydrophilic PTFE membrane wets readily with aqueous, alcoholic, and organic samples without a prewetting step
• 0.45um pore size provides effective particulate removal and sample clarification
• Very low protein binding for improved analyte and protein recovery
• Broadly inert PTFE chemistry supports a pH range of approximately 3 to 12 and good compatibility with aggressive solvents
• Greater effective filtration area helps maintain excellent flow rates

Key Construction Characteristics

• Transparent polypropylene housing, ultrasonically welded and integrity tested to eliminate filter bypass
• 25mm membrane diameter within a 33mm housing, with an effective filtration area of 4.6 cm squared
• Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connections
• Holdup volume less than 100 microliters for efficient recovery of small or costly samples
• Nonsterile, supplied 500 per pack, with each filter labeled by material and pore size

These filters maintain consistent flow and reliable particulate removal to protect downstream instrumentation and preserve sample integrity. The hydrophilic PTFE membrane combines broad solvent compatibility with low protein binding, supporting reproducible analytical results across aqueous and organic workflows.
