Description
Spectra/Por® 7 dialysis membrane is a laboratory dialysis tubing membrane specified with a molecular weight cut-off (MWCO) of 1000 and a flat width of 18 mm. It is intended for dialysis and separation work where controlled retention and exchange across a defined MWCO are required in research or analytical workflows. The 18 mm width suits smaller sample volumes and compact dialysis formats commonly used for buffer exchange, desalting, or fractionation steps. Each unit is supplied as 1 pc with a pack weight of 0,180 kg, making it straightforward to stock beside related dialysis accessories. This membrane from manufacturer REPLIGEN belongs to the established Spectra/Por® 7 series used in filtration, purification, and separation laboratories. Categories covering dialysis hose membranes reflect its role in liquid-phase sample preparation rather than bulk filtration hardware. Laboratories performing biomolecule cleanup, small-molecule removal, or preparatory dialysis can select this width when the 1000 MWCO rating matches the separation target. The clear dimensional specification supports reproducible setup of dialysis bags or tubing segments without guesswork on geometry.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 1000, width 18 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 1000, width 18 mm, 1 unit(s) is the article on this page. Luminix Health distributes REPLIGEN for laboratory use. It sits in Ultrafiltration & concentrators, inside Filtration, in Lab consumables.
An ultrafiltration device holds back macromolecules above a stated molecular-weight cutoff and passes salts and water. It concentrates a protein or exchanges its buffer. The cutoff, the volume and whether it is a centrifugal device or a stirred cell are the specification. A 0.2 µm syringe filter does not do this.
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.
