Grade A-83 Nano-Scale Glass Microfiber Filter, 0.5µm, 150mm, Binderless Borosilicate, 100/Pk SKU: LE-A83-1500

Featuring nano-scale glass microfiber technology delivering exceptional particle retention capacity with precisely controlled 0.5µm pore architecture for high-volume analytical applications. Ultra-fine fiber construction with >85% fiber content between 300nm-1000nm creates one of the highest surface area binderless glass microfiber matrices available, achieving >20x loading capacity compared to equivalent porosity MCE or CN membranes. Hydrophobic borosilicate composition maintains chemical inertness across aggressive solvents while delivering >15x faster flow rates than surface membranes with virtually non-existent back pressure.

Key Nano-Scale Glass Microfiber Characteristics

• Binderless borosilicate construction eliminates sizing additives and surfactants for ultra-low background noise in LC/GC/MS applications
• Precisely regulated 0.5µm particle retention combines membrane-level control with glass microfiber loading capacity
• Exceptional thermal stability enables continuous operation to 500°C for high-temperature analytical protocols
• Smooth glass fiber sheath permits tight consolidation into highly retentive filter matrix with consistent lot-to-lot performance
• High protein affinity with superior washability enables efficient separation recovery and membrane regeneration

Key Construction Characteristics

• 150mm diameter configuration optimizes surface area for high-volume sample processing in analytical and preparative applications
• Chemical stability across all acids except hydrofluoric acid maximizes versatility in aggressive sample matrices
• Independent laboratory verification confirms nano-scale fiber dimensions using SEM image quantification and advanced fiber analysis
• Superior pre-filtration performance extends life of micro-porous membranes including polymeric, track-etched polycarbonate structures
• Uniform thickness and mass distribution matches established Tremont grade specifications for analytical consistency

LE-A83-1500 filters achieve superior particle retention with exceptional flow characteristics, accelerating your sample preparation while maintaining analytical precision for critical separations. Outstanding heat tolerance surpasses polymeric membrane limitations, enabling applications requiring thermal processing up to 500°C. Ultra-low extractables in aggressive solvents combined with verified nano-scale architecture transforms these filters into premium pre-filtration media, delivering validated performance for pharmaceutical processing, environmental analysis, and advanced materials characterization demanding both high-capacity loading and precise particle control.
