Gelatinous precipitate retention
Hardened ashless filter paper is recommended when fast filtration of a gelatinous precipitate for gravimetric analysis is performed on a strongly acidic or alkali solution. Applications of Grade 541 papers include:

• 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
