Description
PTFE membrane filter, 0,2 µm, round filter 47 mm is a laboratory membrane disc made from polytetrafluoroethylene (PTFE) with a pore size of 0,2 µm and a diameter of 47 mm. The round filter format is intended for use in standard holders and filtration assemblies that accept 47 mm membrane discs. Pack size is 100 pc(s), providing a practical quantity for routine sample work and method set-up. Material, pore size and diameter are the defining selection parameters: PTFE as the membrane polymer, 0,2 µm as the stated pore size, and 47 mm as the disc diameter. These attributes support laboratory membrane filtration steps in which a chemically resistant PTFE membrane of this geometry is specified. The unit is listed with a gross weight of 0,10 kg in the product data. Filters of this type from manufacturer Hahnemühle are positioned for analytical and research workflows that call for round PTFE membranes at 0,2 µm and 47 mm. Clear matching of pore size and diameter to existing hardware helps ensure consistent handling across clarification, sample preparation and related filtration tasks in the membrane filter category.

Questions about Membrane filter PTFE ,0.2 µm ,Discs 47 mm
What is this article?
Membrane filter PTFE ,0.2 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.
