Thumbnail Filmstrip of MultiDensity Glass Microfiber Syringe Filter, 0.5µm, 25mm, Hydrophobic, Nonsterile, 100/Pk Images
Featuring multi-layer density glass microfiber technology with proprietary multi pre-filtration stages and final retention down to 0.5µm, delivering accelerated filtration for challenging samples containing lipids, oils, and particulates. Nano-scale glass microfiber construction provides the loading capacity of binderless glass microfiber with tightly regulated pore size control, achieving over 20x loading capacity compared to equivalent porosity MCE or CN membranes with 15x faster flow rates. Borosilicate glass composition delivers exceptional chemical resistance across 0-14 pH range with operational temperature stability from -200 to 500°C.
Key MultiDensity™ Glass Microfiber Characteristics
- Built-in prefilter captures particulates from greater than 300µm and binds difficult-to-filter substances including lipids, petrochemical oils, tars, cellular matter and proteins without clogging
- Chemically inert, pure binderless borosilicate glass construction with no sizing additives or surfactants eliminates contamination risks
- Multiple density zones entrap finer solids rapidly and reliably, yielding faster flow rates with higher fluidic capacity
- Low background noise characteristics for LC/GC/MS applications with very low extractables in aggressive solvents
- Hydrophobic surface chemistry optimizes filtration of organic solvents and non-aqueous solutions
Key Construction Characteristics
- Ultrasonically bonded housing construction ensures leak-proof reliability with filter media type clearly inscribed on barrel
- Luer-Lok™ connection with pressure fitting delivers excellent unit-to-unit and lot-to-lot reproducibility
- Unique concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure
- 25mm diameter configuration provides optimal filtration area for laboratory-scale sample processing
- Nonsterile format ready for immediate use in routine analytical and preparative applications
LE-IWT-ES-10701 filters maximize throughput for viscous samples and turbid liquids requiring multi-stage clarification, delivering superior performance in HPLC sample preparation, GC analysis, and chromatography applications. Outstanding chemical compatibility with acids and bases (excluding hydrofluoric acid) accelerates your analytical workflows while maintaining sample integrity. The innovative MultiDensity™ platform transforms challenging filtration tasks into routine procedures, providing reliable processing of complex matrices that typically overwhelm conventional syringe filters.
