Description
Spectra/Por® 7 dialysis membrane is a dialysis hose membrane specified with a molecular weight cut-off (MWCO) of 15000 and a flat width of 24 mm. It is intended for laboratory dialysis and separation work where solutes are exchanged across a defined MWCO barrier while larger species are retained. The membrane is supplied as 1 pc and belongs to the Spectra/Por® 7 range used in filtration, water purification, dialysis and separation workflows. From manufacturer REPLIGEN, this format supports routine sample handling tasks such as buffer exchange, desalting steps and macromolecule retention according to the stated MWCO. The unit weight is 0,250 kg, matching a compact single-piece pack suited to standard dialysis setups that call for a 24 mm width. Laboratories specifying Spectra/Por® 7 tubing-style membranes can select this MWCO 15000, 24 mm configuration when a defined cut-off and hose geometry are required for method development or day-to-day preparative work. Clear MWCO and width designation help align the membrane with protocol requirements in research and analytical environments without additional grade claims beyond the manufacturer data.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 15000, width 24 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 15000, width 24 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.
