  • 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.
