Description
PES membrane filters with a 0,22 µm pore size and 13 mm diameter are white, smooth disc membranes for laboratory filtration and separation work. The polyethersulfone (PES) membrane format is supplied for use where fine particulate retention and clarification of small sample volumes are required on a compact filter diameter. Each pack contains 100 pieces, supporting repeated analytical, preparative or quality-control filtrations without frequent reordering. The pack weight is 0,015 kg, consistent with lightweight membrane discs for syringe-filter housings, small holders or related filtration hardware. These PES membrane filters from manufacturer MERCK MILLIPORE present a plain white/smooth surface suited to visual inspection and standard handling on the bench. The 0,22 µm pore rating and Ø 13 mm geometry address microfiltration needs in research and routine lab separation workflows. Positioned in the membrane filter category within filtration and separation labware, the discs provide a defined membrane component for users building or maintaining small-scale filtration setups. Laboratories specifying PES media at 0,22 µm can use this 13 mm format for consistent pore size and diameter across multiple filtration steps.
This article is part of Membrane filters, in Filtration.

Questions about PES-membrane filter, white/smooth, Ø 13 mm, pore size 0.22 µm, 100 unit(s)
What is this article?
PES-membrane filter, white/smooth, Ø 13 mm, pore size 0.22 µm, 100 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.
