Description
Folded filter MN 651 1/4 is a fluted laboratory filter paper with a diameter of 32 cm (320 mm) intended for funnel filtration and related laboratory separation work. The pre-pleated design presents a large effective paper surface in the funnel and suits laboratories that require a larger folded format without manual folding of flat sheets. Each pack holds 100 pieces, making it suitable for higher-throughput benches, shared facilities, and teaching laboratories with frequent filter demand. The MN 651 1/4 grade from manufacturer Macherey-Nagel is part of the folded-filter category used in analytical and preparative workflows. Net weight of the pack is 0,86 kg, equal to the gross weight, so the unit remains straightforward to store and issue. Packaging volume is 0,0046784 m³, supporting organised inventory of bulk filter consumables. The 320 mm diameter addresses larger funnel geometries and higher-volume filtration set-ups commonly found in research and industrial laboratories. Because the sheets arrive already folded, set-up is simplified, fold consistency is easier to maintain from piece to piece, and everyday clarification or separation steps can proceed with less preparatory handling before each filtration.

Questions about Folded Filter Papers MN 651 1/4, 32 cm
What is this article?
Folded Filter Papers MN 651 1/4, 32 cm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
