Thumbnail Filmstrip of Grade 113 Qualitative Filter Paper Wet-Strengthened, 150mm Circle, 100/Pk Images
Whatman Grade 113 qualitative filter paper is ultra high loading capacity with a particle retention well suited for use with coarse or gelatinous precipitates. Fastest flow rate of the qualitative grades. Creped surface. Thickest filter paper in the qualitative range.
These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations, etc.
