Grade 934-AH Glass Microfiber Filter, 1.5µm, 24mm, Binderless, High-Temp 550°C, 100/Pk SKU: LE-AH2400

Featuring binderless borosilicate glass microfiber technology delivering exceptional thermal stability and fast flow rates for critical analytical applications. The 1.5µm particle retention capability provides precise suspended solids determination while maintaining superior flow characteristics through depth filtration mechanisms. Hydrophobic surface properties resist moisture interference during high-temperature processing, enabling continuous operation to 550°C without dimensional changes or performance degradation.

Key Borosilicate Glass Microfiber Characteristics

• Binderless construction eliminates organic contamination and maintains analytical purity at extreme temperatures
• 100% borosilicate glass composition delivers exceptional chemical inertness for trace analysis applications
• Fine porosity matrix captures 1.5µm particles while optimizing flow rates in high-volume sampling protocols
• Smooth, uniform fiber structure enables characteristically high flow rates with exceptional small particle retention
• Outstanding thermal stability withstands continuous operation to 550°C for combustion analysis and ash content determinations

Key Construction Characteristics

• Depth filtration mechanism traps particulate within the random fiber matrix, providing high load capacity for gelatinous substances
• Standard 24mm diameter accommodates EPA Method 160.2¹ and Standard Methods 2540D² suspended solids protocols
• Hydrophobic surface chemistry prevents moisture absorption during high-temperature drying cycles
• Nonsterile presentation optimized for analytical laboratory applications requiring post-filtration processing
• Inert glass matrix enables direct gravimetric analysis without interference from filter media constituents

Grade 934-AH filters maximize analytical accuracy in suspended solids content measurements, accelerating processing times even during extended high-temperature analytical protocols. Outstanding chemical resistance to most laboratory reagents and acids provides exceptional versatility for diverse analytical applications including cell harvesting, RIA scintillation counting, and environmental compliance monitoring. EPA Method 160.2¹ and Standard Methods 2540D² compliance transforms these filters into validated reference-grade media, delivering consistent performance for critical water quality assessments and regulatory compliance applications demanding both extreme temperature tolerance and certified analytical precision.
