Grade TSS Glass Microfiber Filter, Total Suspended Solids, 1.5um, 25mm, 100/pk SKU: LE-TSS2500

Featuring binderless borosilicate glass microfiber technology delivering high-efficiency HEPA-type filtration with precise 1.5µm particle retention for EPA Methods 2540C and 2540D^1,2 testing of dissolved and suspended solids in water and wastewater systems. This specialized filtration medium combines exceptional wet strength with ultra-high flow rates and superior loading capacity, eliminating sample contamination through extractable-free construction. Hydrophobic surface chemistry resists moisture interference during TSS analysis while maintaining dimensional stability throughout extended gravimetric procedures.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate glass construction eliminates organic extractables that could interfere with accurate gravimetric analysis
1.5µm particle retention efficiency captures suspended solids including silt, clay, plankton, and organic precipitates
High-efficiency HEPA-type filtration performance ensures complete retention of target analytes for EPA compliance
Superior wet strength maintains structural integrity during vacuum filtration and handling procedures
Optimized porosity matrix delivers exceptional flow rates while maximizing particle loading capacity

Key Construction Characteristics

25mm diameter accommodates standard EPA Method filtration equipment and universal holder configurations
Hydrophobic surface treatment prevents moisture absorption during drying cycles at 103-105°C
Non-sterile glass microfiber medium requires no pre-treatment for routine TSS applications
Ultra-low extractable content supports accurate gravimetric determinations for regulatory compliance
Robust construction withstands repeated drying, cooling, and weighing cycles without degradation

LE-TSS2500 filters achieve reliable performance in total suspended solids analysis, delivering consistent results for environmental monitoring and wastewater treatment compliance testing. Outstanding chemical resistance and thermal stability maximize analytical accuracy when processing complex matrices containing acid mine drainage, industrial effluents, and natural water samples. EPA Methods 2540C and 2540D compatibility^1,2 transforms these filters into validated reference-grade media, providing performance assurance for critical water quality assessments demanding both precision and regulatory compliance in municipal and industrial wastewater treatment applications.
