Whatman
Grade 5V Fluted Fine Particle Filter Paper, 185mm Circle, 100/Pk SKU: 1205-185

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 5V pre-pleated 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 5V fluted filter sheets are suitable for extracting samples from soil to support contaminant testing in the presence of weakly acidic solutions.
