  • Fast filtration speed (Herzberg filtration speed 39 s)
  • High purity (0,015% ash maximum)
  • Acid-treated for high wet-strength and chemical resistance
  • Hardened to minimize fiber shedding

This hard, smooth, high wet-strength Grade 54 fast filter paper enables collection of coarse and gelatinous precipitates with minimal fiber shredding, even when wet.
