Grade VSS Glass Microfiber Filter, 1.5µm, 55mm, Binderless High-Temp, 550°C, 100/Pk SKU: LE-VSS5500

Featuring binderless glass microfiber technology delivering exceptional thermal stability for volatile suspended solids determination in water quality analysis applications. A well-mixed sample is filtered through a glass fiber filter, utilizing specialized 1.5µm pore structure that provides precise particulate retention while maintaining dimensional integrity through continuous 550°C ignition cycles. Proprietary glass chemistry construction exceeds typical borosilicate thermal limits, enabling reliable processing of high-temperature solvents, flue gases, and acidic samples requiring validated gravimetric protocols.

Key Glass Microfiber Membrane Characteristics

• 1.5µm particle retention with high loading capacity optimized for complex pore structure and superior surface area
• Hydrophobic surface chemistry resists moisture interference while providing consistent wetting characteristics
• Proprietary glass blend delivers thermal stability beyond conventional borosilicate formulations for extreme temperature applications
• Low fiber shedding minimizes analytical interference and improves quality assurance in gravimetric determinations

Key Construction Characteristics

• Standard 55mm diameter accommodates EPA Method 160.2¹ sampling equipment and universal filter holder configurations
• Minimal loss on ignition validates chemical purity for accurate volatile/fixed solids differentiation in wastewater analysis
• Fixed and volatile solids ignited at 550°C compliance enables Standard Methods 2540E² protocol implementation
• Nonsterile configuration provides cost-effective solution for routine environmental monitoring applications
• Robust construction withstands vacuum filtration pressures while maintaining structural integrity during sample processing

LE-VSS5500 filters achieve exceptional performance in wastewater treatment plant operation because it offers a rough approximation of the amount of organic matter present in the solid fraction of wastewater, activated sludge, and industrial wastes. Outstanding chemical resistance to high-temperature solvents maximizes your analytical flexibility when processing industrial effluents and environmental samples requiring extreme thermal treatment. EPA Method 160.2¹ and Standard Methods 2540C/2540D² compliance transforms these filters into validated reference-grade media, providing performance assurance for your critical water quality monitoring and volatile suspended solids determinations demanding both analytical accuracy and proven thermal stability.
