Grade B Glass Microfiber Filter, Binderless Borosilicate, 1.0μm, 35mm, Hydrophobic, 100/Pk SKU: LE-B3500

Featuring binderless borosilicate glass microfiber technology delivering exceptional particle retention and high loading capacity for demanding analytical applications. Grade B construction from 100% borosilicate glass microfiber without binders or strengthening agents provides fine porosity with medium to fast flow rate and 1.0µm particle retention. This material is twice as thick as Grade A with a higher loading capacity, delivering superior performance for biochemical separations and solid particle filtration applications requiring reliable depth filtration characteristics.

Key Glass Microfiber Membrane Characteristics

Binderless borosilicate glass construction eliminates organic contamination and maintains chemical purity
Double thickness compared to Grade A provides enhanced loading capacity for high-volume samples
Fine porosity matrix achieves 1.0µm particle retention while maintaining medium to fast flow rates
Hydrophobic surface properties resist moisture interference during gas filtration and prefilter applications
Nominal pore size ratings provide consistent particle retention characteristics

Key Construction Characteristics

Standard 35mm diameter accommodates common filtration equipment and holder configurations
Ideally suited for collection of biochemical polymers precipitated by denaturation
Versatile design functions as solid particulate filter for gases or as prefilter medium
Depth filtration matrix traps particles within random fiber structure for high efficiency retention
Smooth, uniform fiber construction enables characteristically high flow rates with exceptional small particle capture

LE-B3500 filters deliver reliable performance for biochemical polymer collection, gas particulate removal, and prefilter applications where enhanced thickness and loading capacity are critical. Glass fiber construction exhibits high operating temperatures and proves particularly economical for prefilter use, maximizing your analytical flexibility while maintaining the purity standards essential for sensitive laboratory protocols requiring contamination-free filtration media.
