Folded filter papers

Folded filter papers are pre-pleated circles that drop straight into a funnel, giving a larger filtration area and faster flow than a flat circle. Analytical, food and industrial laboratories use folded filter papers for routine clarification where speed and convenience matter.

The 398 Macherey-Nagel listings include the MN 280 1/4 grade in 11 cm, 12.5 cm, 15 cm and 18.5 cm diameters, packed 100 to a box, alongside many other MN grades folded in the same way for different retention characteristics.

Pick the grade for the particle size you need to hold back and the diameter to suit your funnel, remembering that a folded paper should sit fully inside the cone. Lancetech Limited supplies Macherey-Nagel folded filter papers to UK laboratories and can quote on bulk orders.
