General description

Time-saving Whatman qualitative grades are offered in this convenient form, which gives 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

Grade 0858 ½: 7-12 μm (medium fast, grained filter paper)

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.

Features and Benefits

  • 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.
