Whatman Quantitative Filter Paper, Hardened Low Ash, Grade 50, 15 cm, Cytiva, 1450-150

Cytiva® Whatman® Quantitative Filter Paper, Hardened Low Ash, Grade 50, 15 cm, 100 sheets/PK, 1450-150

Features:

• Whatman Grade 50 quantitative hardened low ash filter paper is highly glazed to enable recrystallization of very fine precipitates using Büchner funnel or Hirsch funnel filtration
• Hard, very thin, high wet-strength Grade 50 quantitative filter paper withstands wet handling and precipitate removal by scraping
• With very minimal fiber shedding, they are especially good choice for use as carriers in integrated circuits
• Slow filtration for strong retention of very fine particles
• Thinner filter design (average thickness 115 µm) than most Büchner filter papers
• Nominal particle retention of 2.7 µm
• Slow flow rates (Herzberg filtration speed 2685 s)
• High purity and low ash content (0.015% ash maximum)
• Acid-treated for high wet-strength and chemical resistance
• Hardened to minimize fiber shredding
