Acid
washed filter papers
These quantitative filter papers are manufactured from the highest
quality alpha cotton cellulose, and then acid washed with Hydrochloric
acid, followed by Hydrofluoric acid to substantially reduce levels
of metal oxides such as SiO2, CaO, and Fe2O3. Following acid washing,
all papers are rinsed with
ultra pure water for neutralization.
