PTFE Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 13mm, Luer-Lok, Nonsterile, 100/Pk SKU: LE-IWT-ES10193

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering exceptional chemical resistance and extended operational life for demanding analytical applications. The 0.22µm pore size configuration provides precise particulate retention for aggressive organic substances, highly basic solutions, and hot liquids, while autoclavable polypropylene construction withstands 121°C sterilization protocols. Luer-Lok inlet connections ensure leak-tight syringe interface with concentric funnel barrel design reducing back pressure and maximizing throughput efficiency.

Key PTFE Membrane Characteristics

Hydrophobic membrane delivers the highest chemical compatibility rating for aggressive solvents, acids, and caustic solutions
0.22µm absolute retention efficiently captures fine particulates while maintaining optimal flow characteristics
Capable of filtering aqueous solutions following pre-wetting with alcohol for versatile application flexibility
Glass microfiber prefilter extends membrane life by protecting against viscous samples and high particle loads
Ultrasonically welded construction ensures reliable sealing integrity under pressure and thermal cycling

Key Construction Characteristics

13mm diameter optimizes filtration area while accommodating standard laboratory syringe volumes
Rugged polypropylene housing with autoclave capability to 121°C for 15 minutes supports sterilization protocols
Nonsterile configuration provides cost-effective solution for routine analytical sample preparation
Filter media type clearly inscribed on barrel for immediate identification and traceability
Universal Luer-Lok/pressure fitting compatibility accommodates diverse syringe systems and laboratory equipment

These filters excel in HPLC applications, organic solvent sample preparation and cleanup, dissolution sample analysis, and general sample preparation, particularly for samples subjected to high temperatures or caustic environments. By eliminating interfering materials and fine particles down to the specified pore size, LE-IWT-ES10193 filters deliver cleaner sample extracts with exceptional unit-to-unit reproducibility. Outstanding performance in organic solvent clarification and air venting processes makes these filters indispensable for chromatography applications, vacuum pump line protection, and moisture barrier venting where chemical resistance and thermal stability are critical requirements.
