Filter Paper Folded, qualitative, Grade 595 1/2 GE Whatman

A prepleated filter used for many routine analytical applications in different industries (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, e.g., for ICP/AAS analysis).

  • 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.


Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.
Grade 595 ½: 4-7 µm

Very popular, thin filter paper, medium-fast with medium to fine particle retention.

Also available in flat stock form as Grade 595.

  • Retention portion liquid: 4-7 µm
  • Filtration time Herzberg: 80 s
  • Typical thickness: 160 µm
  • Grammage: 68 g/m2
