Description
Cytiva's Whatman Grade 541 acid hardened cellulose filter paper features high wet-strength, high chemical resistance, and a 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
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
