Grade 054 - Fast Flow Rate, 15 µm, Hardened Ashless Grade Filter Paper - 100 Circles These specially treated hardened ashless grades are available for critical quantitative analyti cal 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 are generally used because of their high chemical resistance to strong acid and alkali. This 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. Grade 054 is also used in air and foodstuffs analysis and for chloride and phosphorous in cement, coal and coke.
