Product Description

520 A 1/2 Folded Filters 240 mm

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 preplating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.
Also available in flat stock form as Grade 520 a.
