Ahlstrom Quantitative Grade 55 Filters (Hardened Ashless)
• Grade 55: 15 µm- Fast Speed
• 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
• This grade is also used in air and foodstuff analysis and for chloride and phosphorous in cement, coal, and coke
• Hardened Ashless Grade (Ash 0.006%)
• This specially treated hardened ashless grade is available for critical quantitative analytical techniques requiring increased wet-strengthed and handling capacity
• These high purity filter papers have a tough, smooth surface free of loose fibers and are ideal for collecting wet precipitates
• Offers a convenient combination of particle retention and flow rate
• Generally used because of their high chemical resistance to strong acid and alkali
Image(s) are representative of the product group and not necessarily the individual product.
