MultiDensity Glass Microfiber Syringe Filter, 0.7µm, 25mm, Nonsterile, 100/pk SKU: LE-IWT-ES-10702

Featuring advanced MultiDensity nano glass microfiber technology delivering optimized multi-stage filtration for challenging samples requiring enhanced particulate capture. Ultra-fine 0.7µm pore structure with integrated prefilter stages provides superior retention of lipids, oils, tars, cellular debris, and proteins while maintaining exceptional flow rates through viscous solutions. Maximum operating temperature of 60°C with polypropylene housing construction ensures reliable performance across diverse analytical protocols.

Key MultiDensity Membrane Characteristics

• Nano-scale glass microfiber combines loading capacity of binderless glass with tightly regulated pore size control for precise particulate separation
• Greater than 20x loading capacity compared to equivalent MCE or CN membranes with 15x higher flow rates accelerating sample processing
• Chemically inert, pure binderless borosilicate glass construction with no sizing additives or surfactants eliminates sample contamination
• Low background noise in LC/GC/MS analysis with minimal extractables in aggressive solvents ensuring analytical precision
• High protein affinity with excellent washability optimizes recovery in biological separations

Key Construction Characteristics

• Reinforced polypropylene housing with secure female luer lock inlet and male luer slip outlet connections prevents bursting under pressure
• Ultrasonically bonded construction delivers leak-proof performance with clearly inscribed filter media identification on barrel
• Concentric funnel-shaped barrel design increases internal volume while reducing back pressure during filtration
• Operating temperature range up to 60°C with compatible fluids, with reduced pressure recommendations at elevated temperatures
• Chemical stability in presence of all acids except hydrofluoric acid maximizes compatibility across analytical methods

Robust glass microfiber construction ensures cleaner sample extracts by removing interfering materials and fine particles prior to injection, delivering exceptional unit-to-unit and lot-to-lot reproducibility essential for HPLC, GC, and dissolution testing applications. Well-suited for general filtration applications requiring high loading capacity, the MultiDensity design processes significantly higher sample volumes than conventional single-stage filters, maximizing your laboratory productivity while maintaining analytical integrity across demanding sample matrices.
