Grade 934-AH Glass Microfiber Filter, Binderless Borosilicate, 1.5µm, 32mm, 100/Pk SKU: LE-AH3200

Featuring binderless borosilicate glass microfiber technology delivering superior depth filtration performance for suspended solids analysis and demanding high-temperature applications. The 1.5µm particle retention capability provides optimal clarification efficiency while maintaining exceptionally fast flow rates for accelerated sample processing. Ultra-pure borosilicate glass construction without strengthening agents or binders enables continuous operation to 550°C, making these filters the analytical standard for EPA Method 160.2¹ and Standard Methods 2540D² total suspended solids determinations.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate glass microfiber construction eliminates organic contamination for trace analysis applications
Exceptional thermal stability withstands temperatures up to 550°C without dimensional change or performance degradation
1.5µm effective particle retention provides precise filtration while maintaining rapid flow characteristics
Inert matrix chemistry delivers contamination-free results for gravimetric analysis and elemental determinations
Uniform fiber distribution creates optimized void space structure maximizing particulate loading capacity

Key Construction Characteristics

Depth filtration technology traps particles throughout the fiber matrix rather than surface retention alone
32mm diameter accommodates standard filtration apparatus and universal filter holder configurations
Hydrophobic surface properties resist moisture interference during analytical procedures and storage
High tensile strength withstands vacuum filtration pressures while maintaining structural integrity during handling
Nonsterile format provides cost-effective performance for routine suspended solids and clarification applications

Grade 934-AH filters achieve characteristically high flow rates optimized for processing samples with elevated particulate concentrations or gelatinous substances, accelerating analytical workflows even during high-volume sample processing campaigns. Outstanding chemical resistance and thermal performance maximize analytical flexibility when processing diverse sample matrices requiring validated protocols. EPA Method 160.2¹ and Standard Methods 2540D² compliance transforms these filters into reference-grade analytical media, providing performance assurance for critical environmental monitoring, cell harvesting, and RIA scintillation counting applications demanding both extreme temperature tolerance and certified analytical accuracy.
