Grade A-83 NanoGF Glass Microfiber Filter, 0.5µm, 47mm, Binderless, High-Temp, 100/Pk SKU: LE-A83-4700

Featuring nano-scale glass microfiber technology delivering exceptional loading capacity with precision pore size control for advanced microfiltration applications. This specialty grade has a particle retention of 0.5µm with >20x loading capacity of an equivalent porosity MCE or CN membrane and >15x the flow rate. Chemically inert, pure binderless borosilicate glass with no sizing additives or other surfactants delivers low background noise in LC/GC/MS and very low extractables in presence of aggressive solvents.

Key NanoGF Glass Microfiber Characteristics

Ultra-fine fiber structure with >85% of fiber content between 300nm-1000nm creates one of the highest surface area binderless glass microfiber products available
Binderless borosilicate construction eliminates organic contamination and maintains chemical purity throughout extended filtration cycles
Back pressure is nearly non-existent in comparison to surface membranes, accelerating processing times for high-volume applications
Superior loading capacity accommodates high particulate concentrations without premature filter clogging or flow restriction
Independently laboratory tested using the latest in fiber analysis and SEM image quantification validates nano-scale fiber claims

Key Construction Characteristics

Standard 47mm diameter provides compatibility with universal filtration equipment and manifold systems
Temperature stability to 500°C enables high-temperature sterilization and sample preparation protocols
Hydrophobic surface chemistry resists moisture interference during solvent-based extractions and analytical procedures
Smooth glass fiber consolidation creates highly retentive filter mat with uniform thickness and consistent performance
Chemical resistance to all acids except hydrofluoric acid maximizes compatibility with aggressive analytical solvents

Grade A-83 filters deliver exceptional protein affinity and washability for separation recovery applications, transforming complex sample preparation workflows. Outstanding pre-filtration performance extends the life of downstream micro-porous membranes including polymeric structures and track-etched polycarbonates. Superior heat tolerance compared to polymeric membranes combined with lot-to-lot consistency ensures reliable analytical results for LC/GC/MS applications demanding both ultra-low extractables and validated nano-scale particle retention.
