Whatman Grade 2V Pre-Folded Filter Paper for Qualitative An analysis, 320 mm circle (100 pcs) 1202-320

Lead time: 12 working weeks

Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles. Widely used for general purpose filtration. Has excellent particle retention and a good filtration speed and loading capacity. Also available in flat stock form as Grade 2. Features:

• Savings in time required to quadrant-fold circles to fit conical Filter funnels in repetitive or multiple analysis.
• 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 prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
