    Time-saving Whatman qualitative grades are offered in folded (prepleated) form, which gives 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 as more filter area is available
    • Maintained flow rate due to the reduction in filter paper contact with funnel side and, 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

    Grade 114V: 25 μm (fast, smooth filter paper)
    Strong filter with very fast flow rate. Ideal for coarse particles and gelantanious precipitates. Smooth surface.
