Cytiva Whatman™ Quantitative Filter Paper: Grade 541 Circles

Description

• Recommended when fast filtration of a gelatinous precipitate for gravimetric analysis is performed on a strongly acidic or alkali solution
• Whatman™ Quantitative Filter Paper: Grade 541 Circles are acid hardened cellulose filters, which reduces ash to an extremely low level
• Whatman hardened ashless quantitative filter papers are acid-hardened to give high wet strength and chemical resistance with extremely low ash content
• They are suitable for a wide range of critical filtration procedures
• Large nominal particle retention for fast analytical filtration
• High wet-strength High chemical resistance to strong acid and alkali suspensions Retention of gelatinous precipitate 22 μm nominal particle retention rating Fast flow rate (Herzberg filtration speed 34 s) Maximum of 0.006% ash concentration Quantitative determination of milk sediment Applications Use as an animal foodstuff filter for determining fiber content Determination of gelatin content in milk and cream Quantification of chloride in cement, as well as chloride and phosphorous in coal and coke
