Quantitative Filter Paper, Grade 54, Ashless, 24 cm Diameter, 10 microns Pore, 100/PK, Ahlstrom, 0540-2400

Ahlstrom® Quantitative Filter Paper, Grade 54, Ashless, 24 cm Diameter, 10 microns Pore, 100/PK, 0540-2400

Features:

• 10 microns, Fast Speed filter paper for quantitative gravimetric techniques
• Medium loading capacity
• Acid-washed and ashless for gravimetric and instrumental analysis
• High purity and uniformity
• 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
• Recommended for fast analysis procedures for unstable precipitates such as silicon, which requires speedy filtration
• For coal, mining, cement, and metallurgical laboratories, Grade 54 is often selected when filtration speed is critical and the precipitate is relatively coarse—common alternative to slower grades such as 74 and 94
• Considered equivalent to Cytiva® Whatman® Grade 41
