WHATMAN Grade 54 Quantitative Filter Paper, Hardened Low Ash

GE Healthcare Life Sciences
Whatman Grade 54 filter paper has high wet strength and a larger nominal particle retention rating than comparable Büchner filtration papers, enabling fast vacuum filtration of coarse precipitates. Whatman Grade 54 filter paper can sustain fast vacuum or suction filtration in a Büchner or Hirsch funnel. The hard, smooth, acid-treated Grade 54 fast filter paper supports collection of coarse and gelatinous precipitates with minimal fiber shredding, even when wet.
