Grade D Glass Microfiber Filter, Binderless, 2.7µm, 37mm, Fast Flow Prefilter, 100/Pk SKU: LE-D3700

Featuring binderless borosilicate glass microfiber technology delivering exceptional particle retention with fast flow rates for high-volume laboratory filtration applications. Coarse porosity design with 2.7µm particle retention provides optimal flow characteristics for repetitive laboratory filtering, while serving as an effective prefilter to extend primary membrane life. Pure borosilicate glass construction eliminates organic binders and strengthening agents, ensuring contamination-free results for critical analytical procedures requiring depth filtration performance.

Key Borosilicate Glass Microfiber Characteristics

Binderless borosilicate glass microfiber construction eliminates organic contamination while maintaining structural integrity during high-volume processing
Coarse porosity matrix with 2.7µm retention efficiently captures larger particulates while maximizing throughput rates
Depth filtration mechanism traps particles within the random fiber matrix throughout the media thickness for superior loading capacity
120 grams per meter squared basis weight provides robust mechanical strength during filtration and handling procedures
Hydrophobic surface chemistry resists moisture interference while maintaining consistent flow characteristics across diverse sample types

Key Construction Characteristics

Standard 37mm diameter accommodates universal filter holders and standard laboratory filtration equipment configurations
Complex pore structure develops as fibers overlap, creating high loading capacity with exceptional particle retention efficiency
Smooth, uniform fiber construction permits characteristically fast flow rates while maintaining retention of fine particles
Autoclavable borosilicate glass withstands sterilization protocols without dimensional change or performance degradation
Nonsterile format provides cost-effective solution for routine laboratory applications requiring reliable prefilter performance

LE-D3700 filters achieve outstanding flow rates optimized for high-volume and repetitive routine laboratory filtering, capturing larger particulates to protect downstream membranes from premature clogging. Superior chemical resistance across a wide pH range maximizes analytical flexibility when processing aqueous solutions containing suspended solids or complex matrices. EPA Method 160.2 compliance¹ for suspended solids analysis transforms these prefilters into validated reference-grade media, providing performance assurance for your water quality testing, sample preparation, and analytical workflows demanding both exceptional loading capacity and reliable filtration consistency.
