Description
Spectra/Por® 7 dialysis membrane is an opaque dialysis hose membrane with a molecular weight cut-off (MWCO) of 25000 and a flat width of 12 mm. It is intended for laboratory dialysis and separation work where solutes below the stated MWCO can exchange while larger species are retained. Supplied as 1 pc, the membrane forms part of the Spectra/Por® 7 range used in filtration, water purification, dialysis and separation applications. From manufacturer REPLIGEN, this opaque MWCO 25000 format suits buffer exchange, desalting and related sample-preparation steps that require a higher cut-off in a narrow 12 mm width. Unit weight is 0,150 kg for the single-piece pack. The combination of MWCO 25000, opaque appearance and 12 mm width gives laboratories a compact hose geometry for protocols that specify this Spectra/Por® 7 configuration. Clear designation of cut-off, opacity and width supports accurate selection against method requirements using only the manufacturer-stated product data.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 25000 opak, width 12 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 25000 opak, width 12 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.
