Grade A-83 Glass Fiber Filter, Nano-Scale Binderless, 0.5µm, 35mm, Ultra-High Surface Area - 100/pk SKU: LE-A83-3500

Featuring nano-scale borosilicate glass microfiber technology delivering exceptional 0.5µm particle retention with >20x loading capacity compared to equivalent porosity membrane filters. Revolutionary fiber construction contains >85% of fibers between 300nm-1000nm, creating one of the highest surface area binderless glass microfiber products available. Ultra-pure borosilicate glass composition with no sizing additives or surfactants provides contamination-free performance for critical analytical applications requiring both high throughput and precise filtration.

• Binderless borosilicate glass construction eliminates organic contamination and maintains chemical purity throughout filtration process
• Nano-scale fiber matrix with >85% fibers between 300-1000nm creates exceptional surface area for maximum loading capacity
• 0.5µm particle retention combines precision filtration with >15x faster flow rates compared to polymeric membranes
• Superior loading capacity exceeds equivalent MCE or CN membranes by >20x while maintaining consistent pore structure
• Hydrophobic surface chemistry with high protein affinity enables effective separation and recovery protocols

• Chemically inert composition withstands all acids except hydrofluoric acid, providing broad solvent compatibility
• Thermal stability to 500°C delivers wider temperature tolerance than any polymeric membrane alternative
• Low background noise in LC/GC/MS analysis with minimal extractables in aggressive solvents ensures analytical precision
• Consistent thickness uniformity and mass distribution provides lot-to-lot reproducibility matching established grades
• Standard 35mm diameter accommodates universal filter holders while optimizing sample processing efficiency

LE-A83-3500 filters achieve nearly non-existent back pressure compared to surface membranes, accelerating your sample processing while maintaining exceptional clarity for turbidity measurement applications conforming to EPA Method 180.1 standards. Outstanding chemical resistance and washable construction maximizes your analytical flexibility for pre-filtration of microporous membranes, track-etched polycarbonates, and monolithic membrane materials. Superior thermal tolerance and ultra-low extractables transform these filters into ideal pre-treatment media for high-temperature analytical protocols demanding both exceptional purity and validated performance reliability.
