Grade E Glass Microfiber Filter, 1.5µm, 42.5mm, Binderless Borosilicate, Fast Flow - 100/Pk SKU: LE-E4250

Featuring binderless borosilicate glass microfiber construction delivering 1.5 µm particle retention with fast flow characteristics for economical suspended particle analysis applications. Fine porosity configuration with fast flow rate provides optimized filtration efficiency while maintaining excellent loading capacity for high-volume processing. 100% borosilicate glass composition without binders or strengthening agents ensures chemical purity and thermal stability for demanding analytical protocols.

Key Glass Microfiber Membrane Characteristics

• Pure binderless borosilicate glass construction eliminates organic contamination and maintains analytical integrity throughout temperature cycling
• Smooth and uniform fiber matrix permits characteristically high flow rates while retaining exceptionally small particles and achieving superior load capacity
• Hydrophobic surface chemistry resists moisture interference during air monitoring and particle collection applications
• Exceptional loading capacity handles high concentrations of particulate and gelatinous substances without premature clogging or breakthrough
• Depth filtration mechanism traps particulate within the random fiber matrix throughout the full thickness of the media

Key Construction Characteristics

• 42.5mm diameter accommodates standard filtration equipment and universal filter holder configurations
• Autoclavable construction enables pre-cleaning and sterilization protocols for sterile filtration applications
• Nonsterile packaging with 100 filters per pack delivers cost-effective processing for routine analytical procedures
• EPA Method 160.2¹ compliance for volatile suspended solids testing and total suspended solids determinations
• Low extractables in presence of aggressive solvents with minimal background noise for LC/GC/MS applications

LE-E4250 filters achieve outstanding performance in suspended particle analysis in water, cell harvesting, pre-filtration and air monitoring applications. Superior chemical inertness maximizes compatibility with acidic and basic solutions while delivering validated results for environmental testing protocols. EPA Method 160.2¹ validation transforms these filters into reference-grade media, providing performance assurance for your critical wastewater analysis, environmental monitoring, and analytical chemistry applications demanding both economic efficiency and regulatory compliance.
