Grade TSS Glass Microfiber Filter, Total Suspended Solids, EPA 2540C/D - 1.5µm, 42.5mm, 100/pk SKU: LE-TSS4250

Featuring binderless borosilicate glass microfiber technology delivering HEPA-type filtration efficiency for EPA Method 2540C and 2540D¹ total suspended solids testing. A 1.5µm pore configuration provides precise particle retention while maintaining exceptional flow rates and high loading capacity for demanding water and wastewater analysis applications. Ultra-pure glass construction with zero extractable additives eliminates contamination sources, delivering reliable gravimetric results for regulatory compliance monitoring and environmental assessments.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate construction eliminates organic contamination and extractable compounds that interfere with gravimetric analysis
• HEPA-type 1.5µm particle retention efficiency captures fine suspended solids including silt, clay, plankton, and organic waste particles
• Hydrophobic surface chemistry maintains dimensional stability and filtration performance during aqueous sample processing
• Exceptional wet strength withstands handling stress during filtration cycles and post-drying procedures without fiber loss
• High loading capacity accommodates elevated suspended solids concentrations without premature filter plugging

Key Construction Characteristics

• 42.5mm diameter accommodates standard filtration apparatus used in EPA water analysis protocols and municipal laboratory settings
• Superior flow rates maximize sample throughput while maintaining quantitative particle capture for time-sensitive testing schedules
• Nonsterile grade optimized for environmental testing applications requiring validated analytical performance without bioburden control
• Consistent porosity matrix ensures reproducible results across batches for quality control and regulatory reporting requirements
• Compatible with standard 103-105°C drying protocols specified in EPA Method 2540D¹ for total suspended solids determination

Grade TSS filters deliver validated performance for dissolved and suspended solids testing in potable water, surface water, and wastewater matrices, accelerating your analytical workflows while ensuring EPA compliance. Outstanding chemical resistance and thermal stability support diverse applications including gravimetric analysis of air pollutants, membrane prefilter applications, buffer clarification, and HPLC mobile phase preparation. EPA Method 2540C/2540D compliance¹ transforms these filters into reference-grade media for environmental monitoring laboratories requiring both exceptional purity and regulatory validation for critical water quality assessments.
