MultiDensity™ Glass Microfiber Syringe Filter, 2.7µm, 25mm, Hydrophobic, 100/Pk SKU: LE-IWT-ES-10707

Featuring proprietary multi-layer glass microfiber technology delivering superior filtration performance for challenging sample preparation applications. Multiple density zones with built-in prefilter construction captures particulate from >300µm while providing final retention down to 2.7µm, enabling processing of viscous samples and difficult-to-filter substances that typically clog conventional membrane filters. 100% borosilicate glass construction withstands operating temperatures up to 500°C while maintaining chemical compatibility with organic solvents and aggressive reagents except hydrofluoric acid.

Key MultiDensity™ Membrane Characteristics

• Binderless borosilicate glass microfiber construction eliminates extractable contamination for superior analytical results
• Built-in prefilter effectively captures lipids, petrochemical oils, tars, cellular matter and proteins without premature clogging
• Multiple density zones entrap finer solids rapidly and reliably while larger particles become entrapped on prefilter layer
• Hydrophobic surface chemistry optimized for organic solvent compatibility and non-aqueous sample processing
• Wide-ranging chemical compatibility with excellent resistance to acids, bases, and organic solvents

Key Construction Characteristics

• Ultrasonically bonded housing construction ensures reliability with filter media type clearly inscribed on barrel
• Luer-Lok™ and pressure fitting connections with concentric funnel-shaped barrel design increases volume and decreases back pressure
• 25mm diameter membrane configuration accommodates standard syringe filter applications and sample volumes
• Maximum recommended operating temperature of 60°C for syringe filter housing with compatible fluids
• Excellent unit-to-unit and lot-to-lot reproducibility ensures consistent filtration performance

MultiDensity™ syringe filters excel in applications requiring high particulate loading capacity and rapid flow rates, particularly benefiting chromatography sample preparation, viscous solution clarification, and analytical workflows involving challenging matrices. These filters handle sample preparation tasks typically considered too challenging for other analytical filter products, bridging the gap between macro and micro analytical filtration. The nonsterile format provides cost-effective filtration for routine analytical applications where sterility is not required, maximizing laboratory efficiency while maintaining the exceptional performance characteristics essential for reliable analytical results.
