Description
Spectra/Por® 7 dialysis membrane is a laboratory dialysis hose membrane for molecular separation work, specified with a molecular weight cut-off (MWCO) of 8000 and a width of 24 mm. It is intended for dialysis procedures in which macromolecules above the cut-off are retained while lower-molecular-weight solutes diffuse freely. The membrane is supplied as 1 pc and weighs 0,250 kg, offering a ready single-unit format for individual experiments. In laboratory categories spanning filtration, water purification, dialysis and separation, this product supports preparatory operations such as desalting, buffer exchange and sample clean-up before downstream steps. Manufactured by REPLIGEN, the Spectra/Por® 7 membrane delivers a stated MWCO of 8000 for consistent cut-off selection during method development and routine purification. The 24 mm width provides a balanced geometry for common tubing-style dialysis setups used in research and quality-control laboratories. Packaged as one piece, it helps match membrane size to sample volume and equipment without surplus inventory. This dialysis hose membrane fits established labware workflows for controlled solute exchange and biomolecule handling under standard laboratory conditions.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 8000, width 24 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 8000, 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.
