Description
Spectra/Por® 4 dialysis membrane is a laboratory dialysis hose membrane specified for a molecular weight cut-off (MWCO) of 12000–14000 and a width of 10 mm. It belongs to the established Spectra/Por® 4 range used for dialysis and separation work in research and analytical laboratories. Supplied as a single unit, the membrane supports routine sample preparation, buffer exchange, and macromolecule separation workflows where controlled retention and passage of solutes are required. The flat width of 10 mm suits smaller sample volumes and compact dialysis setups. This Spectra/Por® 4 membrane from manufacturer REPLIGEN fits standard laboratory dialysis practices within filtration, water purification, dialysis, and separation environments. It is intended for use as dialysis tubing membrane in hose form and integrates readily into existing lab protocols for desalting, purification, and molecular fractionation steps. Pack presentation is one piece, with a product weight of 0,200 kg, making it straightforward to stock for method development and day-to-day laboratory dialysis applications.
This article is part of Ultrafiltration & concentrators, in Filtration.

What is this article?
Spectra/Por® 4, dialysis membrane, MWCO 12000 - 14000, width 10 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.
