Whatman 1827-047 Filter Circles, 47mm Dia, Binder Free Grade 934-AH, 100/pk (PN:1827-047)

Grade 934-AH glass microfiber filters are widely used for total suspended solids (TSS) analysis, water quality testing, and general laboratory filtration. Their high loading capacity and fast flow make them especially suitable for filtering turbid or particulate-rich samples.

This filter offers a nominal particle retention of approximately 1.5 µm, allowing efficient capture of fine particulates while maintaining rapid filtration speed.

The 934-AH filters are manufactured from high-purity borosilicate glass microfiber without binders, which provides excellent chemical resistance, low extractables, and high temperature tolerance for demanding analytical work.

Yes. Grade 934-AH glass microfiber filters can typically tolerate temperatures up to about 500–550 °C, making them suitable for gravimetric analysis and applications that require ignition or drying steps.

The 47 mm diameter is commonly used with standard filter holders, Buchner funnels, and vacuum manifolds for environmental testing, air and water monitoring, cell harvesting, and liquid scintillation workflows.
