Whatman™ Quantitative Filter Papers, Hardened Low Ash Grades, Grade 54
: Cytiva
Whatman Grade 54 hardened low ash quantitative filter paper for Büchner funnel and Hirsch funnel filtration enables fast vacuum suction filtration for recrystallization applications.
- Higher nominal particle retention rating (22 µm) than comparable Buchner funnel filter papers
- 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.
