Grade 55 Quantitative Filter Paper (Ashless)

Ahlstrom manufactures a series of extremely high purity, acid washed filter papers designed for use in the analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linens using ultra-pure, reverse-osmosis water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from the filter to filter. Grade 55 Quantitative Filter Paper (Ashless):

  • Quantitative analysis
  • Low ash content 0.007% (Acid-wash treated)
  • High wet-strength
  • Consistent performance
  • Custom Cut
  • Bulk packaging

Hardened Ashless Grades (Ash 0.006%)

These specially treated hardened ashless grades are available for critical quantitative analytical techniques requiring increased wet-strength and handling capacity. These high purity filter papers have a tough, smooth surface free of loose fibers and are ideal for collecting wet precipitates. Each grade offers a convenient combination of particle retention and flow rate and is generally used because of their high chemical resistance to strong acid and alkali.

Ahlstrom 55: 15µm – Fast Speed

Grade 55 Quantitative Filter Paper (Ashless) is a fast filtering grade for gravimetric analysis of coarse particles and gelatinous precipitates (i.e.: aluminum and zirconium hydroxides) in acid and alkali solutions. Ahlstrom 55 is also used in air and foodstuffs analysis and for chloride and phosphorous in cement, coal, and coke.
