Description
PTFE membrane filter, 0,45 µm, round filter 47 mm is a laboratory membrane disc made from polytetrafluoroethylene (PTFE) with a pore size of 0,45 µm and a diameter of 47 mm. The round filter geometry is intended for standard 47 mm holders and filtration assemblies used across analytical and research laboratories. Pack size is 100 pc(s), giving a convenient stock quantity for ongoing sample work. Defining specifications are the PTFE membrane material, the 0,45 µm pore size and the 47 mm diameter, enabling clear alignment with methods that call for this membrane type and format. Packaged gross weight is listed as 0,10 kg. This PTFE round membrane filter from manufacturer Hahnemühle supports laboratory filtration tasks in which chemical resistance of PTFE together with a 0,45 µm pore rating and 47 mm disc size are specified. Users can integrate the discs into clarification, sample preparation and related membrane filtration workflows. Selection is driven by material, pore size and diameter so that the filter matches existing hardware and protocol requirements within the membrane filter category.

Questions about Membrane filter PTFE ,0.45 µm ,Discs 47 mm
What is this article?
Membrane filter PTFE ,0.45 µm ,Discs 47 mm is the article on this page. Luminix Health distributes Hahnemühle for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
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.
