Fluted filter papers
Ready-to-use paper solutions

Many grades of our qualitative and quantitative filter paper are available as fluted circles. We also offer a selection of prefolded cones, quadrant-folded and pyramid-folded filter papers. These convenient formats eliminate time consuming manual pleating or folding, streamlining operations in busy labs.
Whatman ready-to-use folded filter papers from Cytiva support your application needs, save valuable time and provide ease of use when undertaking repetitive or multiple analyses.

Fluted filter papers
This convenient format has major advantages over flat circles.
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.

Additional folded formats
Qualitative and quantitative grades are now available in several convenient folded formats. These ready-to-use paper filters are available in cone, pyramid, and flat quadrant folded formats, in diameters and grades to support your applications.
Whatman pyramid, flat quadrant-folded and cone filters come in a range of media and diameters, and fit conical funnels. Convenient stacking and packaging options are available.
