Description
Quartz Fibre Filter QFH is a binder-free quartz fibre circular filter with a basis weight of 85 g/m² and a diameter of 47 mm. This round filter is designated product type QFH and is supplied in a pack of 50 pieces for laboratory filtration work. The binder-free construction means the medium consists of quartz fibre without added binders, which is relevant when a pure fibre matrix is preferred. With a 47 mm diameter, the circular format matches common laboratory filter holders and funnels that accept this size. The defined basis weight of 85 g/m² characterises the areal density of the sheet. These circular filters from manufacturer Hahnemühle are intended for routine and analytical laboratory use where quartz fibre round filters in the QFH grade are specified. Each pack contains 50 filters, supporting repeated sample preparation and particulate collection tasks. As a binder-free QFH medium at 85 g/m², the 47 mm round format offers a clear, specification-led option for laboratories that require this diameter and fibre type without binder addition.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about Quartz fibre filter QFH, free of binder ,85 g/sqm ,Discs 47 mm
What is this article?
Quartz fibre filter QFH, free of binder ,85 g/sqm ,Discs 47 mm is the article on this page. Luminix Health distributes Hahnemühle 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.
