Description
Glass microfibre filter grade 13440 is a binder-free glass microfibre filter recommended for analytical and gravimetric analyses as well as for use as a prefilter. This laboratory filtration medium supports sample clarification and solids determination in chemical, environmental and quality-control workflows where binder-free glass fibre media are preferred. The filters are supplied in a pack of 500 pieces with a net weight of 0,150 kg, making them practical for routine high-volume laboratory use. Grade 13440 glass microfibre filters from manufacturer Sartorius are suited to gravimetric procedures and as upstream protection for finer membrane filters. Typical applications include analytical filtration steps, gravimetric analysis of particulates and prefiltration of samples before more selective membrane filtration. As a binder-free glass microfibre grade, the product offers a dependable option for laboratories that require consistent filtration media for quantitative and qualitative work without organic binders that could interfere with certain analyses. These filters form part of standard laboratory consumables for analytical sample preparation and related filtration tasks.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;binder free;44mm;500pc
What is this article?
GFpre-filter;binder free;44mm;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.
