Grade A-83 NanoGF Glass Fiber Filter, 0.5um Retention, 70mm, Binderless Borosilicate, 100/Pk SKU: LE-A83-7000

Featuring revolutionary nano-scale glass microfiber technology that combines the exceptional loading capacity of binderless glass microfiber construction with the precision-controlled pore size typically found only in microfiltration membranes. This innovative Grade A-83 filter delivers >20x loading capacity and >15x flow rate compared to equivalent porosity MCE or CN membranes, while maintaining nearly non-existent back pressure compared to surface membranes. Precise 0.5µm particle retention eliminates the traditional compromise between high capacity and tight pore control, delivering superior performance for demanding analytical applications.

Key NanoGF Membrane Characteristics

Verified nano-scale architecture with >85% fiber content between 300nm-1000nm delivers unprecedented surface area for maximum loading capacity
Pure binderless borosilicate glass construction with no sizing additives or surfactants eliminates extractable contamination
Ultra-low background noise in LC/GC/MS applications with minimal extractables in aggressive solvent systems
Smooth glass fiber sheath enables tight consolidation into highly retentive filter matrix for consistent particle capture
Independent laboratory verification using advanced fiber analysis and SEM image quantification validates true nano-scale performance claims

Key Construction Characteristics

Exceptional thermal stability maintains integrity up to 500°C for high-temperature processing applications
Manufacturing consistency delivers lot-to-lot uniformity comparable to established Tremont grades for reliable analytical results
High protein affinity with excellent washability enables effective separation recovery in biological applications
Optimized as prefilter for microporous membranes including polymeric structures and track-etched polycarbonates
Complete chemical stability in all acids except hydrofluoric acid maximizes compatibility across analytical protocols

LE-A83-7000 filters transform analytical workflows by eliminating the traditional performance trade-offs between membrane and depth filtration technologies. Outstanding compatibility with EPA Method 160.2¹ transforms these filters into validated reference-grade media for total suspended solids determination, while the unique nano-architecture accelerates processing times for high-volume sample preparation. Superior chemical resistance and exceptional temperature tolerance maximize your analytical flexibility across diverse applications from environmental monitoring to pharmaceutical purification, delivering both the precision control of membrane technology and the robust capacity advantages that only true nano-scale glass microfiber construction can provide.
