Description
Dialysis tubing Membra-Cel™ cellulose is a regenerated-cellulose membrane hose intended for laboratory dialysis and separation work. It is specified with a flat width of 77 mm and a molecular weight cut-off (MWCO) of 14 000, allowing retention of larger macromolecules while permitting smaller solutes, salts and buffer components to diffuse across the membrane. The cellulose construction is widely used for buffer exchange, desalting, sample concentration workflows and purification steps in biochemistry and molecular biology. This item is supplied as 1 piece, suitable for cutting to the required length for dialysis bags or continuous tubing setups. Membra-Cel™ dialysis tubing from manufacturer Viskase provides a defined geometry and cut-off that support reproducible equilibration times when used with standard laboratory dialysis protocols. Flat width 77 mm offers a generous internal volume for medium-scale samples, while the MWCO of 14 000 fits many protein and polymer applications. Clear dimensional and cut-off data help users select the correct membrane for research, method development and preparative separation tasks in filtration, water purification, dialysis and related laboratory workflows.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Dialysis tubing Membra-Cel(TM) cellulose, Flat width 77 mm, MWCO 14 000
What is this article?
Dialysis tubing Membra-Cel(TM) cellulose, Flat width 77 mm, MWCO 14 000 is the article on this page. Luminix Health distributes Viskase 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.
