Qualitative Filter Papers - Folded (Prepleated Grades)
Time-saving Whatman qualitative grades are offered in this convenient form,
which have major advantages over flat circles:
Savings in time required to quadrant-fold circles to fit conical filter
funnels in repetitive or multiple analysis
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 because more filter area is available
Maintained flow rate because of the reduction in filter paper contact with
funnel side and, of course, 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 2V: 8μm
Widely used for general purpose filtration. Slightly more retentive than No. 1.
Has excellent particle retention and a good filtration speed and loading
capacity.Grade 113V: 30μm
Very thick and strong filter with creped surface for extremely high loading
capacity, particularly in folded form. Fastest flow rate of any qualitative
grade. Ideal for coarse particles and gelatinous precipitates. Grade 114V: 25μm
Strong filter with very fast flow rate. Ideal for coarse particles and
gelatinous precipitates. Smooth surface.
