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. They are available in different formats as in rolls, sheets, discs and folded filters. Qualitative Papers Filtration rate: the time required to filter 10 ml of distilled water at 20 °C through a free-hanging, fully-wetted disc filter with a diameter of 110 mm folded in quarters. Expressed in seconds (per mm).
