Grade B Glass Microfiber Filter, Binderless Borosilicate, 1.0µm, 55mm, Hydrophobic, 100/Pk SKU: LE-B5500

Featuring binderless borosilicate glass microfiber technology delivering exceptional particle retention and loading capacity for demanding analytical applications. Fine porosity construction with medium to fast flow rate achieves 1.0µm particle retention while maintaining superior chemical inertness through continuous operation up to 550°C. Twice the thickness of Grade A filters with significantly higher loading capacity optimizes processing of biochemical polymers, precipitated proteins, and heavily loaded particulate suspensions requiring validated depth filtration protocols.

Key Glass Microfiber Membrane Characteristics

100% borosilicate glass construction eliminates binder contamination ensuring analytical purity for critical biochemical separations
Ideally suited for collection of biochemical polymers precipitated by denaturation with enhanced protein binding capacity
Smooth, uniform fiber matrix permits characteristically high flow rates while retaining exceptionally small particles
Hydrophobic surface chemistry resists aqueous wetting while maintaining structural integrity during extended filtration cycles
Temperature resistance up to 550°C enables high-temperature gravimetric analysis and sample preparation protocols

Key Construction Characteristics

Depth filtration matrix traps particulate within random fiber structure throughout media thickness maximizing retention efficiency
55mm diameter accommodates standard Buchner funnels and vacuum manifold configurations for versatile laboratory integration
High loading capacity handles concentrated particulate and gelatinous substances without premature clogging
Dual functionality as solid particulate gas filter or membrane prefilter expands application versatility
Autoclavable glass construction supports pre-sterilization protocols while maintaining dimensional stability and filtration characteristics

LE-B5500 filters deliver outstanding performance for liquid clarification, suspended solids analysis, and radioimmune assay applications demanding both fine particle retention and exceptional sample capacity. Particularly useful for heavily loaded fine particulate suspensions and liquid scintillation counting techniques requiring high loading capacity. Chemical inertness across wide pH ranges maximizes compatibility with aggressive solvents and reagents, while binderless construction eliminates organic interference in sensitive analytical methods requiring contamination-free sample processing and reliable quantitative results.
