Grade 113 Qualitative Paper FF 32.0CM 1213-320

• Diameter: 32.0cm; Pore Size: 30µm
• Very thick - strong filter with creped surface for extremely high loading capacity in folded form
• Ideal for coarse particles and gelatinous preciptates - time-saving qualitative grades offered in a convenient form; major advantages over flat circles
• Decreased overall filtration time with extra surface area; normal slow down of filtration speed with loading of particulate is postponed
• Increased total loading capacity since more filter area available; maintained flow rate because reduction in filter paper contact with funnel side and self-supporting shape of filter

Very thick and strong filter with creped surface for extremely high loading capacity in folded form. Fastest flow rate of any qualitative grade. Ideal for coarse particles and gelatinous preciptates. Time-saving Whatman™ qualitative grades are offered in this convenient form which have major advantages over flat circles. Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analysis. Decreased overall filtration time with extra surface area; normal slow down of filtration speed with loading of particulate is postponed. Increased total loading capacity because more filter area is available. Maintained flow rate because of reduction in filter paper contact with funnel side and the self-supporting shape of the filter. Prepleating does not significantly affect any technical data and the same may be used for flat circles. Retention: 30µm.
