Description
Spectra/Por® 6 dialysis membrane with a molecular weight cut-off (MWCO) of 3500 is a laboratory dialysis tubing membrane designed for controlled size-based separation. Featuring a flat width of 45 mm and supplied as 1 pc, it is suited to buffer exchange, desalting, sample clean-up, and depletion of low-molecular-weight contaminants from research samples. Species larger than the MWCO remain inside the tubing while smaller molecules pass into the surrounding dialysate during standard dialysis procedures. This Spectra/Por® 6 membrane from manufacturer REPLIGEN belongs to the dialysis hose membrane category used in filtration, water purification, dialysis, and separation laboratories. The unit weighs 0,350 kg, supporting convenient handling alongside related labware. With an MWCO of 3500, the membrane provides a defined retention threshold for macromolecules, aiding reproducible planning of dialysis duration, buffer changes, and sample loading. Applications commonly include protein and peptide preparation, oligonucleotide processing, and general purification steps that depend on diffusion rather than chromatography. The single-unit pack is practical for individual runs, protocol optimisation, and routine bench work with standard dialysis closures and vessels.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 6, dialysis membrane, MWCO 3500, width 45 mm, 1 unit(s)
What is this article?
Spectra/Por® 6, 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.
