Description
Phosphate-free round filters type MN 619 G are laboratory cellulose filter papers cut as 90 mm diameter discs for filtration tasks that require a phosphate-free medium. This special filter-paper grade is oriented toward applications such as fat analysis, brewery-related filtration and other procedures in which phosphate contribution from the paper should be avoided. Each unit pack holds 100 pc(s) and weighs approximately 0,065 kg, matching common needs in vacuum technology and gravity filtration setups that use round cellulose papers. The filters come from manufacturer MACHEREY-NAGEL as type MN 619 G within the phosphate-free special papers portfolio. The 90 mm diameter provides a generous filtration surface for larger sample volumes or wider funnel formats while retaining the handling simplicity of pre-cut round discs. Typical laboratory uses include clarification, sample preparation and solid–liquid separation before downstream analysis. Uniform sizing across the pack helps maintain reproducible filtration area from disc to disc. The 100-piece configuration is practical for routine laboratory consumption and for stocking shared filtration stations.

Questions about Phosphate-free round filters, type MN 619 G, Ø 90 mm, 100 unit(s)
What is this article?
Phosphate-free round filters, type MN 619 G, Ø 90 mm, 100 unit(s) 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.
