This series of extremely high purity, acid washed filter paper is designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra pure water and further treated with acid to remove any remaining organic and inorganic impurities.
Hardened Ashless Grade (Ash 0.02%)
Grades 371, 372 and 373 are specially treated hardened ashless papers ideal for critical quantitative analysis techniques requiring increased wet strength and handling capacity. They have a tough, smooth surface free from loose fibres and ideal for collecting wet precipitates.
Each grade is widely used because of their high chemical resistance to strong acids and alkali.
