Collection: Quantitative Ashless Filter Papers
Quantitative filter paper is recommended for applications where filtration residues must be quantified once filtering is complete.
Ashless grade quantitative filter papers are manufactured from 100% cotton linters that have undergone both acidic and alkali washes to remove any trace impurities. After this treatment, the ash content is 0.007%.
