Whatman® Folded Qualitative Filter Papers 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 analyses • Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponed • Increased total loading capacity because more filter area is available • Maintained flow rate because of the reduction in filter paper contact with funnel side and, of course, the self-supporting shape of the filter itself • The prepleating does not significantly affect any of the technical data and the same figures may be used for the flat circles
