Description
Spectra/Por® 7 dialysis membrane is a laboratory dialysis hose membrane intended for molecular separation work, specified with a molecular weight cut-off (MWCO) of 3500 and a width of 45 mm. It is used in dialysis procedures where controlled retention of larger species and diffusion of lower-molecular-weight solutes are required. Supplied as 1 pc with a weight of 0,260 kg, the membrane suits individual experimental setups and routine sample-handling tasks. Within filtration, water purification, dialysis and separation workflows, this format supports common operations such as buffer exchange, desalting and preparatory clean-up before downstream analysis. The Spectra/Por® 7 membrane from manufacturer REPLIGEN provides a defined MWCO of 3500, giving a clear cut-off reference for method development and day-to-day purification. The 45 mm width offers a practical geometry for tubing-style dialysis configurations used in research and quality-control laboratories. As a single-unit pack it allows laboratories to match membrane dimensions to sample volume and apparatus without unnecessary bulk. This dialysis hose membrane integrates into established labware protocols for biomolecule handling and solute exchange under standard laboratory conditions.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 3500, width 45 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 3500, width 45 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.
