Description
Glass fibre microfilter, grade GFFA (1,6 µm), Ø 55 mm is a binder-free laboratory filter disc manufactured from 100 % borosilicate glass microfibres. The grade provides very fast filtration together with high retention of fine particles and a high loading capacity, making it suitable for general laboratory use across chemistry, environmental and quality-control applications. With a grammage of 37 g/m², a nominal pore size of 1,6 µm and a thickness of 190 µm, these round filters combine rapid flow with effective particle capture while remaining compatible with elevated process temperatures. They are supplied in packs of 100 pieces at 55 mm diameter for convenient stock management on the bench. Equivalence references include Whatman GF/A, Macherey Nagel GF-1 and Schleicher & Schuell GF50, supporting method transfer and straightforward replacement in established filtration protocols. Offered by manufacturer Labbox, the filters are intended for clarification, prefiltration ahead of membrane steps and analytical sample preparation where glass microfibre media are preferred. The binder-free construction helps minimise extractables and supports clean filtrates in routine workflows that demand both filtration speed and reliable fine-particle retention.

Questions about Glass microfiber filter, GFFA grade (1,6 um), Ø55 mm, 100 pcs
What is this article?
Glass microfiber filter, GFFA grade (1,6 um), Ø55 mm, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
