PTFE Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk
GVS SKU: FJ25BNPPT004AD01

Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.45um pore size, this 25mm syringe filter delivers reliable clarification of aggressive organic solvents, acids, and bases that would compromise other membrane chemistries. The membrane is sealed within a transparent polypropylene housing and configured with a Female Luer Lock inlet and Male Luer Slip outlet for secure, leak-resistant connection to standard syringes. Supplied nonsterile in a pack of 500, it is built for high-throughput sample preparation in analytical laboratories.

Key PTFE Membrane Characteristics

• Naturally hydrophobic: PTFE excels at filtering organic solvents, aggressive chemicals, and gases without wetting out under typical conditions.
• Broad chemical compatibility: Withstands strong acids, bases, and a wide range of solvents, making it well suited to demanding HPLC and GC sample prep.
• 0.45um rated pore size: Removes fine particulates to clarify samples and protect downstream instrumentation.
• Low extractables: The inert membrane chemistry minimizes interference with sensitive analytical methods.

Key Construction Characteristics

• Housing: Transparent polypropylene for solvent compatibility and visual confirmation of sample flow.
• Connections: Luer-Lok inlet and Luer Slip outlet for secure syringe attachment and controlled dispensing.
• Membrane diameter: 25mm, balancing throughput and hold-up volume for routine sample volumes.
• Sterility and pack: Nonsterile, supplied 500 per pack for high-volume workflows.

This filter maintains consistent flow and dependable particulate removal across repeated use, protecting columns and detectors from contamination. The inert PTFE membrane and polypropylene housing preserve sample integrity even with harsh organic chemistries, supporting accurate and reproducible analytical results.

Hydrophobic

• HPLC and GC Sample Preparation Clarifies organic and solvent-based samples to 0.45um before injection, protecting columns and detectors from particulates.
• Organic Solvent Filtration The hydrophobic PTFE membrane filters aggressive solvents that would wet out or degrade other membrane materials.
• Sample Clarification Removes fine particulates from solutions to deliver clean, consistent samples for downstream analysis.
• Acid and Base Filtration Broad chemical compatibility allows safe filtration of strong acids and bases without membrane damage.
• Gas Filtration and Venting The hydrophobic membrane passes gases readily, supporting air and gas filtration tasks.
• Particulate Removal Protects analytical instrumentation by removing suspended solids from process and reagent streams.
