Description
Round filter MN 619 de, 7 cm is a circular laboratory filter paper designed for standard filtration tasks. With a diameter of 7 cm, these discs arrive in packs of 100 pieces and fit common medium-sized funnels used in research and quality-control settings. The MN 619 de grade from manufacturer Macherey-Nagel provides reliable performance for clarifying aqueous samples, retaining particulates and preparing solutions ahead of analysis. The pre-cut round shape ensures uniform geometry and eliminates manual trimming, supporting consistent laboratory practice. Suitable for gravity filtration workflows, the filters handle routine volumes efficiently while remaining easy to position and dispose of after use. A net weight of 0,05 kg per pack underscores the lightweight nature of the paper medium. Laboratories benefit from the ready-to-use format that integrates directly into existing protocols without additional preparation steps. The pack size maintains practical stock levels for daily operations in chemistry, biology and analytical environments, contributing to smooth and reproducible sample-handling sequences.

Questions about Round filter MN 619 de, 7 cm
What is this article?
Round filter MN 619 de, 7 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.
