GR 2 FF 50CM

Grade 2V Pre-Folded Filter Paper for Qualitative Analysis, 500 mm circle (100 pcs)
Compared with quadrant-folded filters, GE’s Whatman Grade 2V pre-folded filter paper exposes extra surface area, which enables a higher loading capacity and shorter filtration time.
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
GE Healthcare’s Life Sciences business offers a broad range of Whatman qualitative filter papers, including standard filter grades and wet-strengthened grades.
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.
