Filters Filter Papers Qualitative Filter Paper
Grade 604½ Qualitative Filter Papers for coarse precipitates. Maintains flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself.

  • Increased total loading capacity as more filter area is available

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.

Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses.
