Description
Vivaspin 20, 30.000 MWCO PES is a centrifugal crossflow spin filter developed for rapid ultrafiltration and diafiltration (UF/DF) of laboratory samples. Featuring a polyethersulfone (PES) membrane with a 30.000 molecular weight cut-off, it handles feed volumes from 0,1 to 98 mL and can deliver concentration factors up to 400× with one filter unit. This performance profile supports concentration, buffer exchange and clarification of macromolecules in controlled spin-filter workflows. Typical uses include ultrafiltration, diafiltration and polishing in research and method-development settings. The product is offered as a pack of 12 pieces from manufacturer Sartorius, matching the Vivaspin 20 geometry used in standard laboratory centrifuges. The 30.000 MWCO PES membrane gives a higher cut-off option within the same device family for samples that require broader permeate passage while retaining larger species. Pack net weight is 0,394 kg, making this smaller pack convenient for targeted series or method trials. Vivaspin 20, 30.000 MWCO PES therefore provides a practical crossflow UF/DF format for efficient sample preparation without leaving conventional centrifuge-based practice.

Questions about Vivaspin 20, 30kDa PES, 12pc
What is this article?
Vivaspin 20, 30kDa PES, 12pc 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.
