Ahlstrom Quantitative Filter Paper (Hardened Ashless)
| |
Ahlstrom manufactures 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.
