Vivaflow® SU is a next generation ultrafilter that simplifies TFF for researchers who value efficiency over complexity. With these kits, you can effortlessly concentrate and rebuffer any macromolecule from up to 500 mL feed samples quickly, reliably, and more sustainably. True Plug and Play- Ready to flow. Pre-defined kits include all the cassettes and tubing sets you need to perform ultrafiltration right out of the box. Thanks to the directional Luer fittings, linking each cassette to a suitable pump and feed and permeate reservoirs is fast and simple. Process Any Molecule- Lossless flexibility. The extended range of membranes includes high-performance Hydrosart® regenerated cellulose (RC), with molecular weight cut-offs (MWCOs) from 2 to 300 kDa. These are ideal for high recovery of proteins, viruses, nucleic acids, and more. Performance Optimized- Put down the calculator. The unique flip flow path has been re-designed from the ground up to enhance ultrafiltration and diafiltration performance. This delivers ultra-efficient TFF without the need for tedious process optimization. Less Single-Use Waste- Responsibly made. Vivaflow® SU cassettes contain 30.5% less plastic than the previous generation and are shipped in easy-to-recycle packaging. The dedicated tubing sets in these kits are also designed to run each cassette individually, so every component serves a purpose.
