Ultrafiltration Device Facilitates Fast Sample Concentration with High Recoveries

Sartorius has introduced the disposable Vivaspin Turbo 15, optimally suited for protein, virus or nanoparticle concentration as well as desalting, dialysis and buffer exchange. It is available in a range of volumes from 4 to 15 ml and permits easy and complete recovery of the concentrate.

With Vivaspin Turbo 15, laboratory technicians can concentrate biological samples within 10 to 30 minutes and obtain macromolecular recoveries of more than 95%. In a single spin, 15 ml solutions can be concentrated up to 150 times. High flow rates are achieved due to the twin vertical membranes, which minimise protein polarisation and subsequent fouling of the membrane. The optimised design and sleek internal profile of Vivaspin Turbo 15 ensures process speeds down to the last few microliters.

The 100 µl dead stop pocket is easy to access with standard 200 µl pipette tips due to the patent pending angular design of Vivaspin Turbo 15. It eliminates the risk of the sample running to dryness while allowing high recovery of the concentrate.

The use of highly chemically resistant plastic materials, such as polystyrene and polypropylene, guarantee a stable shelf life, even in humid environments. Polyethersulfone membranes are preferred for their low fouling characteristics, exceptional flux and broad pH compatibility. The combination of polyethersulfone, polystyrene and polypropylene enables Vivaspin Turbo 15 units to be readily sterilised and depyrogenated.
