Quantitative ashless filter paper Retention:7-9µm - Grade 351 (#42 equivalent) Resistance to β-lactam antibiotics occursThis 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 treat with acid to remove any remaining organic and inorganic impurities. Grades 351, 352 and 354 are high purity filter papers suitable for routine quantitative gravimetric techniques and in the preparation of samples for
