Description:
Ahlstrom Munksjö 0550-4000 40.00cm Hardened Ashless Quantitative Filter Paper, 15.0um Retention. Grade 55 is fast filtering for gravimetric analysis of coarse particles and gelatinous precipitates (i.e.: aluminum and zirconium hydroxides) in acid and alkali solutions. Grade 55 is also used in air and foodstuffs analysis and for chloride and phosphorous in cement, coal, and coke. Ash content is 0.007%.
This specially treated hardened ashless grade is 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. It offers a convenient combination of particle retention and flow rate and is generally used because of its high chemical resistance to strong acid and alkali. 100/pack.
