Description
Dialysis tubing Membra-Cel™ cellulose is a cellulose dialysis membrane supplied as tubing for laboratory dialysis and separation applications. It offers a flat width of 44 mm and a molecular weight cut-off (MWCO) of 14 000, allowing controlled passage of small solutes while retaining larger molecules. Delivered as a 30 m roll, the product gives ample continuous length for preparing numerous dialysis segments or bags matched to experimental volumes. Membra-Cel™ cellulose membranes are standard consumables in dialysis hose membrane use and fit broader labware needs in filtration, water purification, dialysis and separation. This tubing from manufacturer Viskase comes as 1 pc with a weight of 0,260 kg for single-unit stocking. The 44 mm flat width sets the filled cross-section once the tubing is hydrated and sealed, supporting larger sample loads than narrower grades at the same MWCO. Laboratories specify MWCO 14 000 when methods require that retention threshold for desalting, buffer exchange or sample preparation. Roll presentation keeps the membrane easy to store, cut and dispense at the bench for everyday dialysis work.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Dialysis membrane Membra-Cel, 44 mm, 30 m, roll
What is this article?
Dialysis membrane Membra-Cel, 44 mm, 30 m, roll 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.
