PTFE Syringe Filters, 0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk
GVS SKU: FJ25BNPPT002AH01

Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.22um pore size, these 25mm syringe filters deliver fast, reliable filtration of aggressive organic solvents, acids, bases, and gases. The membrane is sealed in a transparent polypropylene housing with a female Luer lock inlet and a male Luer slip outlet, and each unit ships nonsterile in packs of 100. The PTFE chemistry provides outstanding chemical resistance and makes the device well suited to solvent-based sample preparation and vent or gas filtration where aqueous membranes would wet out or degrade.

Key PTFE Membrane Characteristics

• Naturally hydrophobic PTFE chemistry that resists wetting by water while readily passing organic solvents and gases.
• Broad chemical compatibility with strong acids, bases, oxidants, and aggressive solvents.
• 0.22um pore size for fine particulate removal and clarification of solvent-based samples.
• Low protein and analyte adsorption, helping preserve sample integrity for analytical work.
• Ideal for chemical, vent, and gas filtration applications where membrane integrity under solvent exposure is critical.

Key Construction Characteristics

• Transparent polypropylene housing for visual monitoring of sample flow and broad solvent compatibility.
• Female Luer-Lok inlet and male Luer slip outlet for secure syringe connection and convenient dispensing.
• 25mm membrane diameter in a 33mm housing, sized for small to moderate sample volumes.
• Maximum operating pressure up to 75 psi.
• Supplied nonsterile, 100 filters per pack.

This device maintains consistent flow and dependable particle retention across repeated solvent applications, protecting downstream instruments and columns. The hydrophobic PTFE membrane and chemically resistant housing work together to preserve sample integrity during demanding chemical and analytical workflows. Each filter is labeled with its membrane material and pore size for easy identification outside the original packaging.

Hydrophobic

• Solvent and Organic Sample Clarification The hydrophobic 0.22um PTFE membrane clarifies organic solvents and aggressive chemical samples without wetting out.
• HPLC and GC Sample Preparation Removes fine particulates from solvent-based samples to protect columns and improve chromatographic results.
• Acid, Base, and Oxidant Filtration Broad PTFE chemical compatibility supports filtration of strong acids, bases, and oxidizing solutions.
• Vent and Gas Filtration The hydrophobic membrane is suited to sterile venting and process air or gas filtration where aqueous membranes would fail.
• Bulk and Electronics-Grade Chemical Filtration Provides reliable particle removal for bulk chemical and electronics-grade solvent applications.
• Particulate Removal from Nonaqueous Buffers Delivers clarification of solvent-rich buffer and reagent solutions ahead of analysis.
