- 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 the funnel side and the self-supporting shape of the filter itself.
- The pre-plating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
