Grade VSS Glass Microfiber Filter, 1.5µm, 47mm, Binderless, Volatile Suspended Solids, 100/Pk SKU: LE-VSS4700

Featuring proprietary glass chemistry technology delivering superior thermal stability for volatile suspended solids determination applications. Ultra-high temperature resistance beyond typical borosilicate glass enables continuous operation through 550°C ignition protocols required for Standard Methods 2540E fixed and volatile solids testing. Binderless construction with 1.5µm particle retention provides contamination-free gravimetric analysis while maintaining structural integrity during extreme temperature cycling for water quality monitoring and industrial waste characterization.

Key Glass Microfiber Membrane Characteristics

• Binderless glass microfiber construction eliminates organic binder interference during high-temperature ignition cycles
• Proprietary glass chemistry formulation withstands continuous exposure to 550°C without dimensional change or chemical degradation
• 1.5µm particle retention efficiency captures fine suspended solids while optimizing filtration flow rates for high-volume processing
• Superior thermal shock resistance prevents cracking during rapid temperature transitions from ambient to ignition temperatures
• Hydrophobic surface properties resist moisture absorption ensuring accurate gravimetric determinations in humid laboratory environments

Key Construction Characteristics

• Standard 47mm diameter accommodates universal filter holder configurations for routine laboratory protocols
• Low fiber shedding design improves quality assurance by minimizing contamination artifacts in analytical results
• Minimal weight loss percentage during gravimetric testing validates chemical purity for accurate volatile solids calculations
• High loading capacity complex pore structure maximizes sample throughput while maintaining filtration efficiency
• Nonsterile grade optimized for environmental and industrial applications where sterility is not required

LE-VSS4700 filters achieve exceptional performance in Standard Methods 2540C, 2540D, and EPA Method 160.2 compliance applications, delivering validated results for suspended solids content analysis in water quality monitoring programs. Outstanding chemical resistance to high-temperature solvents and flue gases maximizes analytical flexibility when processing challenging industrial samples requiring extreme temperature treatment protocols. Method 2540E compliance¹ transforms these filters into reference-grade media for wastewater treatment plant operation monitoring, providing reliable approximation of organic matter content in activated sludge, industrial wastes, and environmental samples demanding both thermal stability and analytical accuracy.
