Description

General description

A folded filter paper for routine applications with medium retention and flow rate. Covers a wide range of laboratory applications and is frequently used for clarifying liquids.

• 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 prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
• Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

Grade 1V: 11 um
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 1

Features and Benefits

• Nominal particle retention rating of 11 µm supports general filtration
• Intermediate filtration speed (Herzberg 150 s)
• Pre-folded filter for ease-of-use and time savings with conical filter funnels; avoids the need to quadrant-fold circles
