Grade A-83 NanoGF Glass Microfiber Filter, 0.5µm, 42.5mm, Binderless Borosilicate, 100/Pk SKU: LE-A83-4250

Featuring nano-scale glass microfiber technology delivering exceptional loading capacity with precisely controlled 0.5µm particle retention for demanding analytical applications. Grade A-83 combines the loading capacity of binderless glass microfiber with tightly regulated pore size control, achieving >20x loading capacity and >15x flow rate compared to equivalent porosity MCE or CN membranes. Ultra-pure binderless borosilicate glass construction withstands temperatures from -200°C to 500°C with complete chemical resistance to acids and bases (pH 0-14 range).

Key Nano-Scale Glass Microfiber Characteristics

• Certified nano-scale fiber content with >85% of fibers between 300nm-1000nm, creating one of the highest surface area binderless glass microfiber products available
• Chemically inert pure binderless borosilicate glass eliminates sizing additives and surfactants that interfere with analytical protocols
• Near-zero back pressure compared to surface membranes accelerates filtration while maintaining precise particle retention
• Ultra-low extractables and background noise optimize LC/GC/MS performance even with aggressive solvents
• Exceptional protein affinity with high washability enables separation recovery for biochemical applications

Key Construction Characteristics

• Independent laboratory validated using advanced fiber analysis and SEM image quantification to verify nano-scale fiber claims
• 42.5mm diameter accommodates standard filtration equipment and holder configurations for versatile laboratory use
• Wide effective temperature range from -200°C to 500°C with complete chemical stability in all acids except hydrofluoric acid
• Autoclavable glass construction enables pre-cleaning protocols for ultra-trace analysis applications
• 100-pack quantity provides cost-effective supply for high-volume analytical workflows

LE-A83-4250 filters excel as high-performance prefilters for microporous membranes, track-etched polycarbonates, and monolithic membrane materials where conventional polymer membranes fail. Superior thermal tolerance compared to any polymeric membrane maximizes your analytical flexibility across extreme temperature applications. Independent laboratory verification of nano-scale fiber structure ensures consistent lot-to-lot performance, delivering the reliability your critical analytical protocols demand for protein separations, biochemical clarifications, and advanced filtration workflows requiring both exceptional loading capacity and precise particle retention control.
