MultiDensity Glass Microfiber Syringe Filter, 1.2µm, 25mm, Nonsterile, Luer-Lok, 100/Pk SKU: LE-IWT-ES-10704

Featuring proprietary MultiDensity glass microfiber technology delivering accelerated filtration performance through multiple pre-filtration stages culminating in a precise 1.2µm final retention stage. 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. Ultrasonic welding of barrel structure for increased leak / burst resistance ensures reliable sample processing for challenging analytical applications requiring high-volume throughput.

Key MultiDensity Membrane Characteristics

• Multiple density layers optimize flow rates while maintaining 1.2µm particle retention for consistent analytical results
• Hydrophobic glass microfiber construction delivers exceptional chemical compatibility with organic solvents and aggressive reagents
• Faster flow rate with higher fluidic capacity - up to 4x capacity of traditional glass microfiber filters in same porosity range
• Binderless borosilicate glass provides ultra-low extractables for HPLC, GC, and chromatography sample preparation
• Concentric funnel-shaped barrel design increases filtration volume while reducing back pressure during processing

Key Construction Characteristics

• 25mm diameter with female Luer-Lok inlet and male slip outlet accommodates standard syringe connections
• Nonsterile configuration optimized for analytical laboratory applications requiring high-throughput sample processing
• Wide temperature range of -200 to 500°C with pH compatibility from 0-14 maximizes application flexibility
• Polypropylene housing construction provides chemical resistance while maintaining structural integrity under pressure
• Filter media type clearly inscribed on barrel enables positive identification during multi-sample workflows

LE-IWT-ES-10704 filters achieve superior unit-to-unit and lot-to-lot reproducibility, accelerating your analytical workflows when processing viscous solutions, turbid samples, or samples containing cellular debris that typically challenge conventional filtration media. Exceptional chemical resistance to strong acids (except hydrofluoric acid) and bases maximizes your solvent compatibility for diverse extraction and purification protocols. The innovative MultiDensity architecture transforms these filters into high-capacity analytical tools, providing reliable performance for demanding HPLC sample prep, GC injection preparation, and chromatography applications requiring both exceptional particle removal and minimal sample hold-up volume.
