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 pre-pleating does not significantly affect any of the technical data and the same figures may be used for the flat circles

Whatman Grade 2V pre-folded filter paper exposes extra surface area, compared to quadrant folded paper, which enables a higher loading capacity and shorter filtration time.

Features:

  • Medium flow and nominal particle retention rating of 8 µm
  • Herzberg filtration speed of 240 s
  • Fluted (pre-pleated) for easy
  • use with conical filter funnels
  • Can be used for soil analysis or general filtration

Pre-Folded Filters for Seed and Soil Testing

Grade 2V pre-folded filter sheets are suitable for extracting samples from soil to support contaminant testing in the presence of weakly acidic solutions.
