Description
Glass fibre filter GF50 is a binder-free round filter with a basis weight of 56 g/m² and a diameter of 47 mm for laboratory filtration. This grade GF50 medium is made from glass fibre without binders, supporting clean particle retention where additive-free media are preferred. The 47 mm round format fits common filter holders and sample-preparation assemblies used in analytical chemistry, environmental testing and general laboratory practice. Each pack contains 100 pieces, a practical quantity for routine laboratory use. Produced by manufacturer Hahnemühle, the GF50 series combines a defined areal weight of 56 g/m² with binder-free glass fibre construction. Such filters are selected for prefiltration, clarification and particle collection ahead of further analysis. The glass fibre medium offers mechanical stability during handling while remaining free of binder components that could leach into filtrates. Laboratories needing consistent round glass fibre discs will find the 47 mm diameter convenient for standard apparatus. Specified as product type grade GF50 at 56 g/m², the filters support batch-to-batch uniformity in everyday protocols for aqueous samples and compatible organic solvents in membrane-filter workflows.

Questions about Glass fibre filter GF50, free of binder ,56 g/sqm ,Discs 47 mm
What is this article?
Glass fibre filter GF50, free of binder ,56 g/sqm ,Discs 47 mm is the article on this page. Luminix Health distributes Hahnemühle 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.
