Grade A Glass Microfiber Filter, 1.6µm, 150mm, Binderless Borosilicate, Air/Water, 100/Pk SKU: LE-A1500

Featuring binderless borosilicate glass microfiber technology delivering exceptional 1.6µm particle retention with superior flow rates for demanding analytical filtration applications. Produced from 100% borosilicate glass microfiber without binders or strengthening agents, these depth filters utilize smooth and uniform fibers that permit characteristically high flow rates while allowing retention of exceptionally small particles and high load capacity. Grade A filters excel in radioimmuno assay of weak beta emitters by scintillation counting and gravimetric determination of airborne particulate, while hydrophobic surface characteristics resist moisture interference during critical analytical protocols.
