Grade 934-AH Glass Microfiber Filter, Binderless, 1.5µm, 82.6mm, High-Heat 550°C, 100/pk SKU: LE-AH8260

Featuring binderless borosilicate glass microfiber technology delivering exceptional filtration performance for suspended solids analysis and high-temperature applications. The 1.5µm retention efficiency provides precise particle capture while maintaining characteristically fast flow rates through depth filtration principles. Ultra-pure 100% borosilicate glass construction without binders or strengthening agents enables continuous operation up to 550°C, making these filters ideal for EPA Method 160.2¹ and Standard Methods 2540D² compliance testing.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate glass microfiber construction eliminates organic contamination and maintains analytical purity
1.5µm particle retention with exceptional small particle capture efficiency in random fiber matrix
High flow rate depth filtration enables rapid processing while maintaining superior load capacity
Hydrophobic surface chemistry resists moisture interference during critical analytical procedures
Thermal stability to 550°C supports high-temperature analysis protocols and sample preparation

Key Construction Characteristics

82.6mm diameter accommodates standard filtration equipment and analytical protocols
Smooth, uniform fiber structure provides consistent void space and predictable flow characteristics
High load capacity handles concentrated particulate and gelatinous substances without premature clogging
Inert borosilicate matrix enables accurate sediment entrapment for counting and further analysis
Nonsterile format optimized for routine analytical laboratory applications requiring reliable performance

These filters excel in suspended solids content measurements, cell harvesting applications, and RIA scintillation counting where analytical precision is critical. The depth filtration characteristics trap particulates within the random fiber matrix thickness, delivering exceptional efficiency through complex void space structures that develop as fibers overlap. EPA Method 160.2¹ and Standard Methods 2540D² compliance transforms these filters into validated reference media, providing performance assurance for environmental monitoring and wastewater analysis applications demanding both thermal resistance and certified analytical accuracy.
