Description
PES membrane filter 0,22 µm, Ø 142 mm is a polyethersulfone membrane disc for laboratory filtration and separation workflows that require a defined pore size and a large effective diameter. The membrane is white with a smooth surface, supplied in 142 mm diameter format and a pore size of 0,22 µm, supporting clarification and particulate retention steps on appropriate filter holders or process hardware matched to this disc size. Large-diameter PES membranes are commonly selected when higher throughput per filtration cycle is needed compared with smaller discs of the same pore rating. Each pack contains 50 pc(s) and weighs 0,200 kg, which suits method development, routine batch filtration and stockholding in central media preparation or quality-control laboratories. This PES membrane filter from manufacturer MERCK MILLIPORE is offered within membrane-filter assortments for filtration, water purification and separation tasks. Consistent white/smooth presentation aids visual inspection before use and alignment in holders. Specify holder compatibility for 142 mm discs and confirm process suitability of PES for the sample matrix. The combination of 0,22 µm pore size and 142 mm diameter provides a clear geometry for scale-up from smaller analytical membranes when larger volumes must be processed under comparable retention targets.
This article is part of Membrane filters, in Filtration.

Questions about PES-membrane filter, white/smooth, Ø 142 mm, pore size 0.22µm, 50 unit(s)
What is this article?
PES-membrane filter, white/smooth, Ø 142 mm, pore size 0.22µm, 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.
