Sterile PTFE Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 13mm, Luer-Lok, 100/Pk SKU: LE-IWT-ES10198

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering superior chemical resistance for aggressive organic solvents and nonaqueous sample preparation. Luer-Lok connection provides leak-tight syringe attachment while ultrasonically bonded construction ensures reliable seal integrity. Rugged polypropylene housing withstands autoclave sterilization to 121°C for 15 minutes, delivering validated sterile performance for critical laboratory applications requiring contamination-free results.

Key PTFE Membrane Characteristics

• Hydrophobic PTFE construction provides highest chemical compatibility rating for aggressive organic substances and highly basic solutions
• Pre-wetting with alcohol enables aqueous solution filtration while maintaining membrane integrity
• Eliminates interfering materials and fine particles down to 0.22µm pore size ensuring cleaner sample extracts
• Inherently hydrophobic surface chemistry resists water-based contamination during organic solvent processing
• Suitable for clarification of organic solvents and air venting processes in laboratory environments

Key Construction Characteristics

• Integrated glass microfiber prefilter extends membrane life by capturing larger particles before primary filtration
• Concentric funnel-shaped barrel design increases filtration volume while decreasing back pressure during processing
• Ultrasonically bonded assembly eliminates adhesive contamination risks in sensitive analytical applications
• Clear identification markings inscribed on barrel for easy membrane type verification
• Universal Luer-Lok/pressure fitting compatibility accommodates diverse syringe types and laboratory equipment

LE-IWT-ES10198 filters excel in HPLC sample preparation, organic solvent cleanup, and dissolution sample analysis applications requiring high-temperature or caustic environment compatibility. Outstanding chemical resistance to acids, bases, and harsh solvents maximizes your analytical flexibility when processing viscous organic-based samples and chromatography solvents. Sterile individual packaging transforms these filters into validated tools for tissue culture media preparation, biological fluid clarification, and protein filtration protocols demanding both chemical compatibility and contamination control assurance.
