Grade VSS Glass Microfiber Filter, Volatile Suspended Solids, 1.5um, 21mm, Binderless, 100/Pk SKU: LE-VSS2100

Featuring proprietary binderless glass microfiber technology delivering exceptional thermal stability for volatile suspended solids determination and high-temperature analytical applications. The 1.5µm pore structure provides precise particle retention while withstanding extreme temperatures beyond typical borosilicate glass limitations, making these filters ideal for EPA Method 160.2¹ and Standard Methods 2540C, 2540D² compliance protocols. Specialized glass chemistry construction eliminates organic binder contamination while maintaining structural integrity through 550°C ignition cycles required for fixed and volatile solids analysis.

Key Glass Microfiber Membrane Characteristics

Binderless construction eliminates organic interference in gravimetric analysis while providing superior thermal stability for high-temperature applications
1.5µm particle retention efficiency captures fine suspended solids while optimizing flow rates for rapid filtration of water and wastewater samples
Proprietary glass chemistry withstands continuous operation beyond standard borosilicate limits, enabling reliable performance in extreme temperature environments
Low fiber shedding characteristics improve analytical precision and reduce contamination risk during critical water quality determinations
High surface area complex pore structure maximizes loading capacity while maintaining consistent filtration performance throughout extended sampling protocols

Key Construction Characteristics

Hydrophobic surface chemistry resists moisture interference during ambient and heated sample preparation procedures
Standard 21mm diameter accommodates universal filter holders and sampling equipment configurations for seamless integration
Nonsterile grade optimized for routine environmental monitoring applications requiring validated analytical performance without sterility requirements
Low percentage weight loss during ignition at 550°C ensures accurate gravimetric determinations for volatile suspended solids content
Glass fiber matrix construction provides chemical resistance to aggressive solvents and corrosive sample matrices encountered in industrial wastewater analysis

Grade VSS filters excel in determination of fixed and volatile suspended solids using Standard Method 2540E ignited at 550°C², delivering reliable performance for treatment plant operators analyzing organic matter content in wastewater, activated sludge, and industrial waste streams. Outstanding thermal stability through extreme temperature cycles accelerates your analytical workflows while maintaining measurement accuracy critical for regulatory compliance. EPA Method 160.2¹ compliance transforms these filters into validated reference-grade media for total suspended solids determinations, providing performance assurance for your critical water quality monitoring and environmental assessment applications demanding both precision and regulatory approval.
