Description
Vivaspin 20 Diafiltration Cups are laboratory accessories developed for continuous diafiltration together with Vivaspin 20 centrifugal concentrators. They are intended to eliminate separate process steps through continuous diafiltration and to minimize buffer consumption, with the design aimed at achieving 98% salt removal in a single spin. This approach is useful when samples must be desalted or transferred into a new buffer without lengthy multi-step washing sequences. Supplied as a pack of 12 pieces from manufacturer Sartorius, the cups address applications such as salt or detergent removal, buffer exchange, sample pH adjustment, low-molecular-weight contaminant removal, and addition of preservatives, inhibitors or cofactors. Non-sterile supply suits general laboratory sample preparation alongside Vivaspin 20 ultrafiltration devices. Their role is to streamline polishing and conditioning of macromolecular samples during or after concentration. With a net weight of 0,060 kg per pack, they offer a compact consumable option for research groups that routinely perform diafiltration, desalting and buffer exchange in the Vivaspin 20 workflow.

Questions about Vivaspin 20 Diafiltration Cups, 12pc
What is this article?
Vivaspin 20 Diafiltration Cups, 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.
