PTFE Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
GVS SKU: FJ25BNPPT004AH01

Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.45um pore size, these 25mm syringe filters deliver fast, reliable clarification of aggressive chemicals, organic solvents, acids, bases, and gases. The membrane is housed in a transparent polypropylene housing measuring 33mm in diameter, with a female Luer-Lok inlet and male Luer slip outlet for secure connection to standard syringes. Each nonsterile unit provides broad chemical compatibility and a low holdup volume to protect costly samples and downstream instrumentation.

Key PTFE Membrane Characteristics

• Naturally hydrophobic structure ideal for filtering acids, bases, oxidants, and nonaqueous solvents
• Exceptional broad chemical compatibility for aggressive and bulk chemical filtration
• 0.45um pore size provides effective particulate removal and sample clarification
• Well suited to sterile venting and process air or gas filtration applications
• Low inherent extractables for clean, reproducible analytical results

Key Construction Characteristics

• Transparent polypropylene housing, 33mm diameter, autoclavable for up to 5 cycles
• Female Luer-Lok inlet and male Luer slip outlet for secure syringe attachment
• Nonsterile, supplied 100 per pack
• Holdup volume less than 50 microliters to minimize sample loss
• Maximum operating temperature of 90 degrees C and maximum operating pressure of 80 psi

This filter delivers consistent, high throughput filtration while maintaining sample integrity across demanding chemical and solvent applications. The integrity tested construction eliminates potential filter bypass, and the low holdup volume preserves valuable or limited sample volumes. Each unit is labeled with the membrane material and pore size for easy identification outside its original packaging.
