Description
Polyethersulfone membrane filter 0,20 µm is a non-sterile round membrane disc with a diameter of 25 mm, intended for laboratory filtration workflows that require a defined PES membrane. The hydrophilic polyethersulfone (PES) material supports aqueous and many aqueous-organic sample streams where a nominal pore size of 0,20 µm is specified for fine particulate retention and clarification steps. Supplied as plain round filters, the discs fit standard 25 mm filter holders and related laboratory filtration hardware used in sample preparation, buffer work-up and analytical prefiltration. These membranes from manufacturer Hahnemühle are delivered non-sterile, so they suit applications in which sterilisation is not required or is performed by the user according to local protocols. Pack size is 100 pc(s), supporting routine bench use and multi-sample series without frequent restocking. The compact 25 mm format keeps hold-up volume low while remaining easy to handle with forceps. Gross weight of the packed unit is 0,08 kg. Choose this PES round filter when a clear 0,20 µm pore rating and 25 mm diameter are needed for consistent laboratory membrane filtration.

Questions about Membrane filter Polyethersulfone ,0,20 µm, non-sterile ,Discs 25 mm
What is this article?
Membrane filter Polyethersulfone ,0,20 µm, non-sterile ,Discs 25 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.
