Ashless hardened filter paper for qualitative analysis
These filter papers are used for qualitative analysis.
Qualitative filters are made of refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, which gives them a number of diverse filtration properties.
The ash content of less than 0.06% is not reduced by post-treatment.
Qualitative filter papers are available in sheets, discs and folded filters.
