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
