  • 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
