Description
Vivaspin 500, 50.000 MWCO PES is a crossflow spin filter for fast ultrafiltration and diafiltration of small laboratory samples. The polyethersulfone (PES) membrane is rated at a 50.000 molecular weight cut-off and supports feed volumes from 0,1 to 98 mL, enabling concentration factors up to 400× with a single device. These units are intended for UF/DF workflows such as sample concentration, buffer exchange, polishing and diafiltration when only limited volumes are available. The compact Vivaspin 500 format fits routine benchtop centrifuge protocols and helps streamline macromolecule handling without multi-step transfers. Packaged as 25 pieces and offered by manufacturer Sartorius, the filters suit research and analytical sample-preparation tasks that require reliable retention at the stated MWCO. Non-sterile construction matches general laboratory consumable use. Net weight is 0,100 kg per pack. Designed as original crossflow spin filters, they combine practical volume range with high single-pass concentration performance for efficient protein and biomolecule processing.

Questions about Vivaspin 500, 50kDa PES, 25pc
What is this article?
Vivaspin 500, 50kDa PES, 25pc 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.
