Ahlstrom 0540-2700 Quantitative Filter Paper, 10 Micron, Fast Flow, Grade 54, 27cm Diameter (Pack of 100)

A series of extremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters 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 filter to filter. Quantitative analysis, low ash content 0.007 percent (acid-wash treated), high wet strength, consistent performance, hardened grades, custom cut. These standard ashless grades are high purity filter papers suitable for routine quantitative gravimetric techniques and in the preparation of samples for use in analysis involving instrumental techniques. This is a fast filtering grade for rapid filtration of coarse particles and gelatinous precipitates such as iron, zirconium and aluminum hydroxides, and cobalt sulfide. Grade 54 is also used in air pollution testing to determine gaseous compounds. It is recommended for fast analysis procedures for unstable precipitates such as silicon, which requires speedy filtration. 34 sec/100mls Filtration speed herzberg. 200 mls/min Filtration speed rapidity. Medium loading capacity.
