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 postponedSavings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analysesIncreased total loading capacity as more filter area is availableThe prepleating does not significantly affect any of the technical data and the same figures may be used for the flat circlesCellulose filters are used in qualitative analytical techniques to determine and identify materialsPrepleated qualitative filters give improved flow rate and increased loading capacity compared to equivalent quadrant folded filters
