MultiDensity Glass Microfiber Syringe Filter, 1.0µm, 25mm, Hydrophobic, Nonsterile, 100/Pk SKU: LE-IWT-ES-10703

Featuring proprietary MultiDensity™ nano glass microfiber technology delivering optimized multi-stage filtration for challenging samples containing lipids, oils, tars, and particulate matter. Built-in prefilter captures particulate from >300μm and binds typically difficult to filter substances without clogging such as lipids (natural oils and waxes), petrochemical oils, tars, cellular matter and proteins. The graduated density structure provides exceptional loading capacity while maintaining consistent 1.0µm final retention, accelerating processing of viscous solutions and heavily contaminated samples requiring reliable prefiltration.

Key MultiDensity Membrane Characteristics

• Multi-layer density gradient construction speeds filtration while preventing premature clogging from difficult-to-filter substances
• Binderless borosilicate glass microfiber delivers superior chemical compatibility with aggressive solvents, acids, and bases
• Hydrophobic surface chemistry optimizes performance with organic solvents and non-aqueous sample matrices
• 1.0µm final retention stage ensures precise particulate removal after multi-stage prefilter conditioning
• Exceptional dirt-loading capacity exceeds standard membrane filters through depth filtration structure throughout media thickness

Key Construction Characteristics

• Ultrasonic bonding technology ensures reliable seal integrity and eliminates contamination from adhesives or thermal welding
• Medical-grade polypropylene housing provides chemical resistance while maintaining dimensional stability under pressure
• Luer-Lok™ inlet connection delivers secure syringe attachment during high-volume sample processing
• Concentric funnel-shaped barrel design increases sample volume capacity while reducing back pressure during filtration
• Clear media identification inscribed on barrel enables instant verification of filter specifications during laboratory workflows

LE-IWT-ES-10703 filters deliver exceptional unit-to-unit reproducibility and lot-to-lot consistency, ensuring reliable performance across extended analytical campaigns. The proprietary MultiDensity construction maximizes throughput for challenging samples including tissue culture media, petrochemical extracts, and biological matrices requiring both coarse prefiltration and precise final retention. Outstanding chemical inertness with minimal extractables makes these filters ideal for HPLC, GC, and LC-MS sample preparation applications demanding both high loading capacity and analytical precision.
