Grade 934-AH Glass Microfiber Filter, Binderless Borosilicate, 1.5µm, 47mm, 550°C, 100/pk SKU: LE-AH4700

Featuring binderless borosilicate glass microfiber technology delivering exceptional thermal stability and chemical resistance for critical analytical applications. The 1.5µm particle retention rating provides precise filtration while maintaining fast flow rates optimized for suspended solids determinations and related measurements. 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 construction eliminates organic contamination and maintains analytical purity at elevated temperatures
1.5µm particle retention with depth filtration matrix captures exceptionally small particles while delivering characteristically high flow rates
Superior thermal stability withstands continuous operation to 550°C without dimensional change or performance degradation
Smooth, uniform fiber structure permits high load capacity for concentrated particulate and gelatinous substances
Hydrophobic surface chemistry resists moisture interference during gravimetric analysis protocols

Key Construction Characteristics

47mm diameter provides compatibility with standard filtration apparatus and EPA-approved sampling equipment configurations
Depth filtration design traps particulate within random fiber matrix, maximizing retention efficiency for complex void space structures
Inert glass matrix enables sediment entrapment for further analysis and counting without matrix interference
Nonsterile grade optimized for analytical testing where sterility is not required, reducing costs for routine monitoring
100-pack quantity ensures consistent supply for high-volume testing laboratories and environmental monitoring programs

LE-AH4700 filters excel in suspended solids content measurements, delivering validated performance for EPA Method 160.2¹ Total Suspended Solids protocols and Standard Methods 2540D² compliance testing. Outstanding prefiltration capabilities accelerate your analytical workflows when paired with membrane substrates for surface filtration applications. The binderless construction maximizes your analytical accuracy for cell harvesting applications and RIA scintillation counting, providing contamination-free results essential for precise quantitative determinations and regulatory compliance reporting.
