Grade B Glass Microfiber Filter, 1.0µm, 150mm, Binderless Borosilicate, High Loading - 100/Pk SKU: LE-B1500

Featuring binderless borosilicate glass microfiber technology delivering exceptional retention of 1.0µm particles with superior loading capacity for biochemical polymer collection and liquid clarification applications. This material is twice as thick as Grade A with a higher loading capacity, providing extended filtration cycles while maintaining excellent flow rates. Ultra-pure construction from 100% borosilicate glass microfiber without binders or strengthening agents ensures chemical inertness and minimal background interference for critical analytical protocols.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate construction eliminates organic contamination and maintains sample purity throughout processing
High loading capacity with fine particle retention maximizes filtration efficiency while extending service life in demanding applications
Hydrophobic surface chemistry resists aqueous interference during biochemical polymer precipitation and denaturation processes
1.0µm retention efficiency captures fine precipitates while optimizing flow rates for routine laboratory filtration
Depth filtration matrix traps particulate within the random fiber structure, with efficiency determined by complex void space overlap

Key Construction Characteristics

150mm diameter accommodates standard laboratory filter holders and vacuum filtration apparatus configurations
Smooth and uniform fiber construction permits characteristically high flow rates while allowing retention of exceptionally small particles
Double thickness design compared to Grade A filters delivers enhanced structural integrity and loading capacity
Nonsterile format ready for immediate use in routine clarification and prefilter applications
Compatible with organic solvents and aggressive media, excluding hydrofluoric acid solutions

LE-B1500 filters achieve optimal performance in biochemical polymer collection applications, particularly effective for precipitated proteins and immunoglobulins requiring high-capacity depth filtration. Outstanding chemical resistance to most laboratory solvents and reagents maximizes compatibility across diverse analytical protocols. Glass fiber filter construction complies with EPA Method 160.2 requirements¹ for water quality analysis, providing validated performance assurance for your environmental and analytical testing applications demanding both exceptional loading capacity and reliable particle retention.
