Grade A Glass Microfiber Filter, Binderless, 1.6µm, 37mm, Fast Flow, 98% Efficiency, 100/pk SKU: LE-A3700

Featuring binderless borosilicate glass microfiber technology delivering 98% efficiency at 1.6 µm particle retention with exceptionally fast flow rates for time-sensitive laboratory procedures. 100% borosilicate glass microfiber construction without binders or strengthening agents creates smooth, uniform fibers that enable characteristically high flow rates while maintaining retention of exceptionally small particles and high load capacity. Ideally suited for radioimmuno assay of weak beta emitters by scintillation counting and gravimetric determination of airborne particulate.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate glass construction eliminates organic contamination and maintains chemical inertness for analytical purity
1.6 µm nominal particle retention at 98% efficiency captures fine precipitates while optimizing throughput in high-volume applications
Exceptionally fast flow rates with high dirt-holding capacity accelerates filtration cycles and extends filter life during demanding procedures
Excellent thermal stability withstands temperatures over 500°C for high-temperature analytical and industrial applications
High-purity borosilicate glass microfibers are biologically inert and resistant to most solvents and reagents except hydrofluoric acid and concentrated alkali solutions

Key Construction Characteristics

37mm diameter accommodates standard laboratory filtration equipment and universal filter holder configurations
Smooth, uniform fiber structure permits characteristically high flow rates while allowing retention of exceptionally small particles
High load capacity particularly important in applications involving high concentrations of particulate or gelatinous substances
Inert matrix ideal for entrapping sediment for further analysis and counting without introducing artifacts or contamination
Hydrophobic surface chemistry resists moisture interference while maintaining consistent performance across diverse analytical protocols

Frequently used in the filtration of precipitated proteins and cells, these filters deliver validated performance for biochemical assays, environmental monitoring, and analytical determinations requiring both speed and precision. Commonly used for pre-filtration prior to surface filtration with substrates such as membranes, maximizing downstream filter efficiency and extending membrane life. Suited for a variety of applications involving large sample volumes such as water and air pollution monitoring and wastewater filtering, providing the analytical flexibility your laboratory demands for critical environmental compliance and research applications.
