General description

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

Grade 597 ½ : 4-7 μm (medium fast filter paper)

A medium fast filter paper with medium to fine particle retention. Used for a wide variety of analytical routine applications in different industries like food testing (e.g., determination of fat content) or removal of carbon dioxide and turbidity from beverages (e.g., beer analysis).

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.
