Grade A-83 NanoGF Glass Fiber Filter, Binderless Borosilicate, 0.5µm, 32mm, 100/pk SKU: LE-A83-3200

Featuring revolutionary nano-scale glass microfiber technology combining the exceptional loading capacity of binderless glass depth filters with the tightly controlled pore size precision of microfiltration membranes. This specialty grade delivers 0.5 µm particle retention while maintaining greater than 20x loading capacity and 15x flow rate compared to equivalent porosity MCE or CN membranes. Chemically inert, pure binderless borosilicate glass construction eliminates sizing additives and surfactants for contamination-free analytical results.

Key Nano-Scale Glass Microfiber Characteristics

Validated nano-scale architecture with greater than 85% fiber content between 300nm-1000nm creates one of the highest surface area binderless glass microfiber products available
Independent laboratory tested and SEM image quantified to verify authentic nano-scale fiber claims beyond typical marketing statements
Minimal back pressure compared to surface membranes enables high-throughput processing without pump strain or extended processing times
Ultra-low extractables and background noise in LC/GC/MS applications ensures reliable results with aggressive solvents
Hydrophobic surface chemistry resists moisture interference during filtration while maintaining consistent pore structure integrity

Key Construction and Performance Characteristics

100% borosilicate glass microfiber construction without binders or strengthening agents maintains chemical purity for critical analysis applications
Exceptional thermal stability enables continuous operation up to 500°C for high-temperature analytical protocols
32mm diameter accommodates standard laboratory filtration equipment and provides 8.04 cm² effective filtration area for optimal sample throughput
Chemical resistance to all acids except hydrofluoric acid maximizes compatibility with diverse analytical sample matrices
Superior wet strength and handling durability compared to conventional glass microfiber filters reduces breakage during filter changes

LE-A83-3200 filters transform challenging sample preparation workflows by delivering membrane-level retention precision with depth filter advantages, accelerating your analytical cycles without compromising data quality. Outstanding performance as pre-filters for micro-porous membranes, track-etched polycarbonates, and monolithic membrane materials extends primary filter life while reducing operating costs. EPA Method 160.2 compliance¹ validates these filters for water quality analysis and suspended solids determination, providing regulatory confidence for your environmental monitoring and wastewater analysis applications.
