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.
