      Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

      Grained, with medium fast flow rate and medium retention. A universal Filter paper, used for the filtration of extracts, oils, beer, syrups etc.; also applied in Filter presses or for the aspiration of liquids. Available flat stock form as Grade 858.

      Features:
      • 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 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.
