Description
Vivapore® Solvent Absorption Concentrator 7.5 kDa Polyethersulfone is a ready-to-use laboratory device for equipment-free concentration of proteins and other macromolecules. The polyethersulfone membrane with a 7.5 kDa molecular weight cut-off supports gentle handling of shear-sensitive samples while enabling high concentration factors through simple solvent absorption. Operation follows a straightforward fill-and-go workflow: load the sample and allow concentration to proceed without centrifuges, pumps, or external pressure systems. Typical laboratory uses include macromolecule concentration, desalting, and buffer exchange in research and analytical workflows. Supplied as a pack of 30 pieces from manufacturer Sartorius, the unit is suited to routine sample preparation where reproducible, low-shear concentration is required. Net weight is 0,957 kg. The design focuses on convenience and sample integrity, making it a practical choice for laboratories that need reliable solvent-absorption concentration without dedicated hardware.

Questions about Vivapore 10, 7.5kDa, 30pc
What is this article?
Vivapore 10, 7.5kDa, 30pc 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.
