Description
CTA Membrane with 20.000 MWCO and 25 mm diameter serves laboratory ultrafiltration and diafiltration processes involving macromolecules. It is compatible with traditional and legacy stirred cells and is recommended for custom applications. Flexible options suit ultrafiltration (UF) and diafiltration (DF) of most macromolecules. Popular applications include concentration and protein removal (UF), buffer exchange and desalting (DF), and electroultrafiltration (EUF). Offered in packs of 10 pieces from manufacturer Sartorius, these non-sterile CTA membrane discs provide a 20.000 molecular weight cut-off for selective retention. Diameter is 25 mm and net weight is 0,016 kg. The compact disc format fits standard stirred-cell hardware used for concentration, desalting or buffer exchange. This membrane supports workflows in which larger macromolecules must be retained while smaller species and buffer components pass, enabling efficient sample preparation and protein handling under routine laboratory conditions.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Ultrafilter, 20kDa CTA, 25mm, 10pc
What is this article?
Ultrafilter, 20kDa CTA, 25mm, 10pc is the article on this page. Luminix Health distributes Sartorius 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.
