High-purity, Qualitative Filter Paper
High-purity, Qualitative Filter Paper

These paper grades are used for analytical purposes that require a low ash content.

Grades 292 and 292a are especially suitable for soil analyses because they are low in nitrogen. For phosphate or sodium determination, we recommend grades 131 and 132.
