Grade 2V pre-folded filter sheets are suitable for extracting samples from soil to support contaminant testing in the presence of weakly acidic solutions. Compared with quadrant-folded filters, Cytiva'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 8µm
• Herzberg filtration speed of 240s
• 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
