Grade TSS Glass Microfiber Filter, Binderless HEPA-Type, 1.5µm, 125mm, EPA 2540C/2540D, 100/Pk SKU: LE-TSS1250

Featuring binderless borosilicate glass microfiber technology delivering HEPA-type filtration efficiency for total suspended solids (TSS) analysis in water and wastewater applications. A precise 1.5µm pore configuration provides optimal particulate retention while maintaining exceptional flow rates and high-capacity processing capabilities. Ultra-high purity construction with zero added extractables eliminates sample contamination risks during EPA Methods 2540C¹ and 2540D² protocols for dissolved and suspended solids determinations.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass construction eliminates organic extractables that could interfere with gravimetric analysis results
• HEPA-type filtration efficiency with 1.5µm particle retention captures fine particulates while optimizing sample throughput
• Exceptional wet strength maintains structural integrity during extended filtration cycles and aggressive sample handling
• Hydrophobic surface chemistry resists moisture interference during drying protocols at 103-105°C temperature ranges
• High-capacity design maximizes sample volume processing while maintaining consistent flow characteristics throughout analysis

Key Construction Characteristics

• 125mm diameter accommodates standard EPA-approved filter holders and laboratory filtration apparatus configurations
• Nonsterile specification optimized for environmental water testing where sterility is not required but purity is critical
• Superior chemical resistance to acids, bases, and organic solvents commonly encountered in wastewater analysis protocols
• Minimal ash content ensures accurate gravimetric determinations without interference from filter residue during ignition steps
• 100-pack configuration provides consistent lot-to-lot performance for high-volume laboratory operations and regulatory compliance testing

LE-TSS1250 filters achieve validated performance for EPA Methods 2540C and 2540D^1,2 suspended solids protocols, accelerating your analytical workflows while ensuring regulatory compliance for environmental monitoring applications. Outstanding flow rate characteristics with high-capacity retention maximize your sample processing efficiency when analyzing silt, clay, plankton, organic wastes, and inorganic precipitates from acid mine drainage. Superior wet strength performance transforms these filters into reliable analytical media, providing measurement accuracy for your critical water quality assessments, HPLC eluent clarification, and membrane support applications demanding both chemical purity and mechanical durability.
