Description
Spectra/Por® 7 dialysis membrane is a laboratory dialysis tubing membrane specified at MWCO 1000 with a flat width of 45 mm. It is used in dialysis and separation workflows where a defined molecular weight cut-off controls which species are retained or exchanged across the membrane wall. The 45 mm width provides a relatively wide format for larger sample loads or dialysis setups that benefit from greater internal volume compared with narrower tubing. Each pack contains 1 pc and weighs 0,250 kg, supporting orderly storage alongside other dialysis hose membranes and separation consumables. This membrane from manufacturer REPLIGEN continues the Spectra/Por® 7 series employed in filtration, purification, and dialysis laboratories. Explicit MWCO and width values allow method authors to document membrane selection clearly for buffer exchange, desalting, or preparatory fractionation steps. Research, process-development, and analytical teams can choose this width when the 1000 MWCO rating matches the intended separation window. Standardised geometry simplifies cutting, filling, and sealing of dialysis segments for repeatable bench-scale work.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Spectra/Por® 7, dialysis membrane, MWCO 1000, width 45 mm, 1 unit(s)
What is this article?
Spectra/Por® 7, dialysis membrane, MWCO 1000, 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.
