Description
Glass fibre filter, 70 mm is a circular laboratory filtration disc made from glass fibre and finished with a hydrophilic binder for dependable wetting in aqueous work. The 70 mm diameter fits common funnels and holders used for routine clarification, particle collection, and sample preparation. Hydrophilic binder chemistry encourages rapid, uniform wetting of the fibre matrix, supporting stable flow under gravity or vacuum and reducing handling issues that can occur with poorly wetted media. Supplied in a practical pack of 50 pieces, the format suits everyday bench consumption in research, quality-control, and teaching laboratories. These filters from manufacturer filtraTECH are intended as standard laboratory consumables wherever a robust glass fibre medium with hydrophilic character is preferred. Typical uses include general laboratory filtration, pre-filtration ahead of finer membranes, and processing of suspensions that benefit from the mechanical strength of glass fibre. The combination of glass fibre structure and hydrophilic binder allows straightforward wet use without extra conditioning steps often needed for hydrophobic discs, making this 70 mm filter a convenient round-filter option for daily analytical and preparative workflows.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about Glass microfibres filter, 70 mm
What is this article?
Glass microfibres filter, 70 mm is the article on this page. Luminix Health distributes filtraTECH 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.
