Grade 2V Pre-Folded Filter Paper for Qualitative Analysis

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

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.
