Whatman 1827-085 Filter Circles, 85mm Dia, Binder Free Grade 934-AH, 100/pk (PN:1827-085)

Grade 934-AH filters are widely used for total suspended solids (TSS) analysis, environmental monitoring, air pollution testing, and general laboratory filtration. Their combination of high flow rate and strong particle retention makes them suitable for large-volume liquid filtration.

This filter grade offers approximately 1.5 µm particle retention, allowing efficient capture of fine particulates while maintaining fast filtration speeds.

The binder-free borosilicate glass microfiber structure is chemically inert and minimizes extractables. This design delivers high loading capacity, consistent results, and reliable performance in demanding analytical applications.

This model features an 85 mm diameter, Grade 934-AH glass microfiber media, and comes in a pack of 100 filters. It is hydrophilic and designed for fast filtration with high retention efficiency.

Grade 934-AH is preferred when higher flow rates and fine particle retention are required. Compared to cellulose filter paper, glass microfiber filters typically handle heavier particulate loads and filter large sample volumes more efficiently.
