詳細

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 287 ½: kieslghur paper
Application specific cellulose filter paper. Kieselguhr paper with a medium to slow flow rate. Additional adsorption effect, e.g., for the separation of very fine semi-colloidal turbidity, for clarifying milk serum, starch solutions, soil suspensions or sugar-containing solutions prior to polarimetry or refractometry.
