Grade B Glass Microfiber Filter, Binderless Borosilicate, 1.0um, 42.5mm, Hydrophobic, 100/Pk SKU: LE-B4250

Featuring binderless borosilicate glass microfiber technology delivering superior particulate retention for biochemical and analytical applications. Fine porosity construction with medium to fast flow rate achieves 1.0µm particle retention, while enhanced thickness provides twice the loading capacity of Grade A filters. 100% borosilicate glass construction without binders or strengthening agents ensures chemical purity and thermal stability for demanding laboratory protocols.

Key Glass Microfiber Membrane Characteristics

• Binderless borosilicate glass construction eliminates organic contamination and maintains analytical purity
• 1.0µm nominal pore size with fine porosity captures small particles while optimizing flow rates
• Ideally suited for collection of biochemical polymers precipitated by denaturation
• Smooth and uniform fiber matrix permits characteristically high flow rates while retaining exceptionally small particles
• Double thickness compared to Grade A delivers higher loading capacity for extended filtration cycles

Key Construction Characteristics

• Depth filtration matrix traps particulate within random fiber structure, with efficiency determined by complex void space overlap
• 42.5mm diameter accommodates standard laboratory filter holders and vacuum manifold systems
• Versatile performance as solid particulate filter for gases or effective prefilter applications
• Hydrophobic surface properties resist moisture interference during gas phase filtration
• 100-pack configuration provides convenient laboratory supply for routine analytical procedures

LE-B4250 filters achieve exceptional analytical performance for protein precipitation, cell harvesting, and radioimmunoassay applications requiring validated particulate retention. Characteristically high flow rates optimize processing efficiency during sample preparation and clarification procedures. Inert glass matrix enables reliable sediment entrapment for subsequent analysis and counting, while proven prefilter capabilities extend membrane filter life in multi-stage filtration protocols, maximizing your analytical throughput and cost-effectiveness.
