Description
Spectra/Por® 7 dialysis membrane with a molecular weight cut-off (MWCO) of 3500 is a narrow dialysis hose membrane for laboratory separation and sample preparation. The 18 mm flat width is appropriate for compact dialysis systems and smaller working volumes in research and analytical environments. Supplied as 1 pc with a weight of 0,140 kg, this membrane supports dialysis operations such as buffer exchange, desalting and fractionation steps where an MWCO of 3500 is specified. Spectra/Por® 7 products from manufacturer REPLIGEN are applied in filtration, water purification, dialysis and separation laboratories that require clearly defined cut-off and width parameters. Pairing MWCO 3500 with an 18 mm profile helps align membrane choice with sample size and apparatus geometry. As a dialysis hose membrane, it fits routine protocols for conditioning macromolecular samples. Transparent unit and dimensional information simplifies ordering and bench setup. This variant is intended for labware use whenever Spectra/Por® 7 tubing with MWCO 3500 and 18 mm width is required.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 3500, width 18 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 3500, 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.
