Description
Spectra/Por® 6 dialysis membrane with a molecular weight cut-off (MWCO) of 25000 is an opaque laboratory dialysis tubing membrane for size-based separation of solutes. It has a flat width of 12 mm and is supplied as 1 pc, supporting buffer exchange, desalting, sample clean-up, and removal of lower-molecular-weight species from research preparations. Molecules above the stated MWCO are retained inside the tubing while smaller solutes diffuse into the external dialysate under conventional dialysis conditions. This opaque Spectra/Por® 6 format from manufacturer REPLIGEN is intended for dialysis hose membrane use in filtration, water purification, dialysis, and separation laboratories. The unit weighs 0,220 kg, which is practical for routine handling and storage with other labware. An MWCO of 25000 defines a higher retention threshold suited to larger macromolecules, helping scientists set dialysis times, buffer volumes, and sample loads with clearer expectations. Typical applications include protein workflows, polymer or biomolecule clean-up, and general purification steps that rely on controlled diffusion. The single-unit pack fits individual experiments, method development, and standard bench setups using common dialysis closures and vessels.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 6, dialysis membrane, MWCO 25000 opaque, width 12 mm, 1 unit(s)
What is this article?
Spectra/Por® 6, dialysis membrane, MWCO 25000 opaque, 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.
