Grade A-83 Glass Fiber Filter, Nano-Scale, Binderless - 0.5µm, 25mm - 100/pk SKU: LE-A83-2500

Featuring nano-scale glass microfiber technology delivering exceptional 0.5µm particle retention with superior loading capacity and ultra-high flow rates. Binderless borosilicate glass construction with >85% fiber content between 300nm-1000nm provides unmatched surface area characteristics while maintaining complete chemical inertness for demanding analytical applications. This specialty grade combines the high loading capacity of conventional glass microfiber with the precisely controlled pore structure of microfiltration membranes.

Key Glass Microfiber Membrane Characteristics

Nano-scale fiber matrix with >85% fiber content between 300-1000nm delivers one of the highest surface area profiles available in binderless glass microfiber products
Exceptional loading capacity exceeding 20x that of equivalent porosity MCE or CN membranes maximizes filtration volume before replacement
Superior flow rates >15x faster than comparable surface membranes with virtually non-existent back pressure for high-throughput applications
Binderless borosilicate glass construction eliminates sizing additives and surfactants preventing contamination in LC/GC/MS analysis
Hydrophobic surface chemistry resists moisture interference while maintaining consistent 0.5µm particle retention efficiency

Key Construction Characteristics

Chemically inert pure borosilicate glass withstands all acids except hydrofluoric acid for broad solvent compatibility
Smooth glass fiber sheath enables tight consolidation into highly retentive filter matrix with exceptional lot-to-lot consistency
Outstanding thermal stability to 500°C provides significantly wider temperature tolerance than any polymeric membrane alternative
High protein affinity with excellent washability characteristics optimizes separation recovery in bioprocessing applications
Standard 25mm diameter fits universal filter holders while robust tensile strength (ASTM D828)¹ ensures handling integrity during installation

LE-A83-2500 filters achieve remarkable filtration performance optimized for pre-filtration of microporous membranes, including polymeric structures, track-etched polycarbonates, and monolithic membrane materials. Ultra-low extractables in aggressive solvents combined with minimal background noise maximizes your analytical precision in LC/GC/MS applications demanding contamination-free processing. Independent laboratory validation using advanced SEM image quantification confirms authentic nano-scale fiber dimensions, delivering verified performance characteristics that exceed conventional "nano-scale" claims while providing exceptional consistency and analytical reliability for your most demanding separation and clarification applications.
