Description
Round filter MN GF-4, 12,5 cm is a circular laboratory filter intended for routine filtration tasks in analytical, chemical and life-science workflows. With a diameter of 12,5 cm it fits common funnels and filtration holders used for sample clarification, particle retention and preparation steps. The MN GF-4 grade delivers consistent media characteristics that support reproducible results across multiple runs. Each pack contains 100 individual filters, providing a practical quantity for daily laboratory consumption without frequent reordering. Produced by Macherey-Nagel, these round filters are supplied ready for immediate use in research, quality-control and teaching environments. The circular format simplifies handling and placement, while the defined diameter ensures compatibility with standard glassware and apparatus. Suitable for aqueous and many organic solvents depending on the specific protocol, the filters help maintain clean filtrates and protect downstream instrumentation. Laboratories appreciate the uniform size and reliable performance that streamline filtration procedures and reduce variability between samples. The compact pack of 100 pieces stores conveniently and supports efficient inventory management in busy lab settings.

Questions about Glass fiber filters MN GF-4, 12.5 cm
What is this article?
Glass fiber filters MN GF-4, 12.5 cm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Glass & quartz fibre filters, inside Filtration, in Lab consumables.
Glass-fibre and quartz-fibre filters are depth filters with a high dirt load, used for air sampling, for total suspended solids and in front of a membrane. They have no sharp pore-size cutoff the way a membrane does. Binderless grades matter when the filter will be weighed or heated.
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.
