Description
Vivaflow 200, 5.000 MWCO PES is a research laboratory tangential flow filtration (TFF) cassette for concentrating and rebuffering samples at a 5.000 molecular weight cut-off. The PES membrane delivers a defined MWCO for TFF, so retained species can be enriched while buffer composition is adjusted through controlled permeate removal. The format is aimed at TFF that is simple to implement in research laboratories, allowing concentration and rebuffering with minimal optimization and re-use of each cassette without membrane replacement. Common applications cover buffer exchange, concentration and fractionation, making the cassette suitable for preparatory steps ahead of analysis or further processing. It is supplied as 1 pc, non-sterile, with a net weight of 1,171 kg and a gross weight of 1,180 kg. This Vivaflow 200 configuration from manufacturer Sartorius pairs a 5.000 MWCO PES membrane with a reusable cassette body for bench-scale work. Laboratories gain a compact TFF option that supports repeated concentration and exchange cycles without continuous membrane change-out, helping keep sample-prep routes efficient when a mid-range MWCO is required for the target molecules.
This article is part of Ultrafiltration & concentrators, in Filtration.

Questions about Vivaflow 200, 5kDa PES, 1pc
What is this article?
Vivaflow 200, 5kDa PES, 1pc 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.
