Quantitative Filter Paper - 0540-0470 - Grade 54, 4.70cm 54 and microscopyAhlstrom Munksj 54 10 m, Fast Speed This is a fast filtering grade for rapid filtration of coarse particles and gelatinous precipitates such as iron, zirconium and aluminum hydroxides, and cobalt sulfide. Grade 54 is also used in air pollution testing to determine gaseous compounds. It is recommended for fast analysis procedures for unstable precipitates such as silicon, which requires speedy filtration. (100 circles box) Call for pricing if ordering
