Description
Glass microfibre filter Grade 13440 is a binder-free glass microfibre filter for laboratory filtration. It is recommended for analytical and gravimetric analyses and as a prefilter ahead of finer media. The binder-free construction suits workflows where extractable binder residues should be avoided during quantitative or compositional work. Pack size is 500 pieces, with a net weight of 0,200 kg per pack, supporting high-throughput benches that consume filters regularly. Typical use includes sample clarification, particle collection for weighing, and protective prefiltration before membrane stages in chemistry and life-science laboratories. Non-sterile Grade 13440 media fit general analytical protocols rather than aseptic processing. Origin is Germany, with regional sourcing in Niedersachsen. This grade from manufacturer Sartorius integrates into standard filtration trains where glass microfibre depth media are specified for gravimetry, analytical retention, or as a first barrier to protect downstream membranes. Select this pack when binder-free glass microfibre filters of Grade 13440 are required for routine analytical and gravimetric filtration tasks.

Questions about GFpre-filter;binder free;50mm;500pc
What is this article?
GFpre-filter;binder free;50mm;500pc is the article on this page. Luminix Health distributes Sartorius 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.
