具有高湿强度的中速滤纸。该滤纸具有与 1573 级相同的化学耐受性。
- 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.
Whatman 定性级滤纸便于使用，节省时间，与平面圆形滤纸相比，具有很大的优势。
