Qualitative Filter Paper - Standard Grades

Starlab Scientific Qualitative filter papers are particularly suited for general laboratory filtration. The average ash content is about 0.1%. These qualitative filter papers are essentially used for analytical and routine analyses, when no gravimetric analyses are required. They are wet strengthened and can be used for pressure and vacuum filtration.
