Description
PES membrane filter 0,45 µm, Ø 90 mm is a larger-diameter laboratory membrane for filtration and separation workflows. The disc is white and smooth, with a pore size of 0,45 µm and a diameter of 90 mm, suited to holders and funnels that require greater filtration area. Designated as a PES-membrane filter, it uses polyethersulfone membrane material appropriate for clarifying aqueous and compatible laboratory samples. This variant is supplied in packs of 50 pc(s), a practical quantity for the larger 90 mm format. The membranes come from manufacturer MERCK MILLIPORE and serve routine particle-retention and sample-preparation steps in research and analytical laboratories. Pack weight is 0,140 kg, remaining convenient for shelf storage and bench restocking. Clear specification of pore size and diameter helps ensure correct membrane selection when protocols call for 0,45 µm retention on a 90 mm disc. The white/smooth finish supports straightforward visual checks and handling during filter installation.
This article is part of Membrane filters, in Filtration.

Questions about PES-membrane filter, white/smooth, Ø 90 mm, pore size 0.45 µm, 50 unit(s)
What is this article?
PES-membrane filter, white/smooth, Ø 90 mm, pore size 0.45 µm, 50 unit(s) is the article on this page. Luminix Health distributes MERCK MILLIPORE for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
