Grade E Glass Microfiber Filter, Binderless Borosilicate, 1.5µm, 47mm, 100/Pk SKU: LE-E4700

Featuring binderless borosilicate glass microfiber technology delivering exceptional filtration performance with fast flow rates and 1.5µm particle retention. Fine porosity construction with fast flow rate and 1.5µm size particle retention optimizes processing efficiency across suspended particle analysis, cell harvesting, pre-filtration and air monitoring applications. 100% borosilicate glass microfiber construction without the use of binders or strengthening agents ensures chemical inertness while maintaining structural integrity throughout demanding laboratory protocols.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate composition creates an inert matrix ideal for sediment entrapment and further analysis without contamination from strengthening agents
Smooth and uniform fiber construction permits characteristically high flow rates while allowing retention of exceptionally small particles and high load capacity
Autoclavable glass construction enables sterilization protocols for aseptic applications and enhanced analytical reliability
Depth filtration matrix traps particulate within the random fiber structure throughout the full thickness of the media for maximum retention efficiency
Hydrophobic surface characteristics resist moisture interference while maintaining consistent pore structure during extended filtration cycles

Key Construction Characteristics

47mm diameter accommodates standard laboratory filter holders and provides optimal filtration area for routine analytical work
Temperature stability up to 500°C withstands high-temperature processing and incineration protocols for gravimetric analysis
Standard Methods 2540D¹ compliant construction for total suspended solids determination in water and wastewater analysis
100-filter packaging ensures consistent availability for high-volume laboratory operations while maintaining sterility and handling convenience
High particulate concentration tolerance handles gelatinous substances without premature clogging or flow rate degradation

LE-E4700 filters achieve economical processing for suspended particle analysis in water, cell harvesting, pre-filtration and air monitoring applications while delivering the analytical precision required for regulatory compliance testing. Ideal pre-filtration performance prior to surface filtration with membrane substrates extends primary filter life and reduces processing costs in multi-stage filtration systems. Standard Methods 2540D compliance¹ ensures validated performance for total suspended solids protocols, providing the analytical reliability essential for environmental monitoring and water quality assessment applications requiring both speed and accuracy.
