Grade E Glass Microfiber Filter, Binderless Borosilicate - 1.5µm, 125mm - 100/pk SKU: LE-E1250

Featuring binderless borosilicate glass microfiber technology delivering exceptional flow rates and precise 1.5µm particle retention for economical suspended solids analysis and air monitoring applications. Temperature resistance up to 500°C combined with fine porosity and fast flow rate characteristics make this material the standard for volatile suspended solids content and related measurements (Standard Methods 2540D and EPA Method 160.2)^1,2. Depth filtration matrix traps particulate within the complex void structure while maintaining characteristically high flow rates for water treatment, cell harvesting, and pre-filtration protocols.

Key Glass Microfiber Membrane Characteristics

100% borosilicate glass microfiber construction eliminates binders and strengthening agents for ultra-pure analytical applications
Fast flow rates with high load capacity deliver efficient processing of heavy, turbid samples while retaining very fine particles
1.5µm particle retention efficiency captures suspended solids with optimal flow characteristics for analytical protocols
Exceptional thermal stability withstands continuous operation to 500°C without dimensional change or performance degradation
Inert matrix construction prevents sample contamination during sediment entrapment and analytical counting procedures

Key Construction Characteristics

Depth filter design retains particles on surface and traps them within fiber structure for maximum loading capacity
Characteristically high flow rates optimize single and multi-process removal of sediment and coarse particulate
Economical and effective pre-filtration performance extends final membrane filter life by capturing larger particles and high particulate loads
Standard 125mm diameter accommodates universal filter holder configurations and laboratory filtration equipment
Ideal prefiltration medium prior to surface filtration with membrane substrates in analytical workflows

LE-E1250 filters achieve outstanding chemical resistance and inert performance characteristics, accelerating your analytical cycles for water quality monitoring and environmental compliance applications. EPA Method 160.2¹ and Standard Methods 2540D² compliance transforms these filters into validated reference-grade media for suspended solids determination. Binderless construction maximizes analytical accuracy by eliminating organic contamination sources, providing reliable performance for your critical water treatment monitoring, cell harvesting, and pre-filtration applications demanding both economic efficiency and analytical precision.
