Description
Phosphate-free round filters type MN 619 G with a diameter of 240 mm are specialised cellulose filter papers intended for laboratory filtration where phosphate residues must be kept out of the sample path. The circular format fits standard funnels and filtration assemblies used in vacuum and gravity workflows. Each pack contains 100 pc(s) and has a stated weight of 0,410 kg, supporting routine analytical and preparative work without frequent restocking. These filters belong to the special filter-paper group used when phosphate-free media are required, including contexts such as fat analysis, brewery laboratories and related separation tasks. Produced by manufacturer MACHEREY-NAGEL, the MN 619 G grade offers a practical large-diameter surface for medium- to higher-volume filtrations while remaining compatible with common laboratory glassware and holders. Laboratories performing phosphate-sensitive determinations can integrate the discs into existing cellulose filter-paper procedures for clarification and sample preparation ahead of further instrumental steps. The defined 240 mm diameter and consistent round geometry help maintain reproducible handling across multiple preparations. Packaged as 100 units, the product suits continuous bench use in chemical, environmental and quality-control settings that rely on phosphate-free filtration media.

Questions about Phosphate-free round filters, type MN 619 G, Ø 240 mm, 100 unit(s)
What is this article?
Phosphate-free round filters, type MN 619 G, Ø 240 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.
