Prepleated Qualitative Circles: Grade 2V

From $99.95
List Price From $112.00
GE Whatman Prepleated Qualitative Circles: Grade 2V offer savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses. These papers decrease overall filtration time because of the extra surface area exposed. This postpones the loading of the particulate which can slow down of filtration speed.

They create an increased total loading capacity by making more filter area available.These filter papers maintain the flow rate due to the reduction in filter paper contact with the funnel side and the self-supporting shape of the filter itself. Pre-pleating does not significantly affect any of the technical data and the same figures may be used for the flat circles.

Grade 2V: 8 µm is widely used for general purpose filtration. It has excellent particle retention and a good filtration speed and loading capacity. It is also available in flat stock form as Grade 2. Grade 2 is slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). It is more absorbent than Grade 1. In addition to general filtration in the 8 µm particle size range, the extra absorbency is utilized. Grade 2 is also used for monitoring specific contaminants in the atmosphere and in soil testing.

Key Features
  • These filter papers increase total loading capacity with more filter area
  • Maintain flow rates because of the reduction in filter paper contact
  • Decrease overall filtration time because of more available surface area
