Description
Glass fibre microfilter grade GFFA (1,6 µm) is a binder-free circular filter made from 100 % borosilicate glass microfibres for general laboratory filtration. With a pore size of 1,6 µm, grammage of 37 g/m² and thickness of 190 µm, it delivers very fast flow while retaining fine particles and offering high loading capacity. The 90 mm diameter discs withstand elevated temperatures, supporting routine clarification, prefiltration and sample preparation where thermal stability matters. Supplied as a pack of 100 pieces from manufacturer Labbox, these round filters are suited to everyday analytical and process work. Performance is positioned as equivalent to established grades such as Whatman GF/A, Macherey-Nagel GF-1 and Schleicher & Schuell GF50, helping laboratories standardise methods across brands. The pure glass-fibre matrix avoids binder extractables and maintains consistent retention under demanding throughput. Ideal for busy labs needing reliable, high-capacity microfiltration in a convenient 100-piece format.

Questions about Glass microfiber filter, GFFA grade (1,6 um), Ø90 mm, 100 pcs
What is this article?
Glass microfiber filter, GFFA grade (1,6 um), Ø90 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.
