Vivaspin® Turbo 4 is the optimal solution for protein concentration from dilute samples such as after chromatography, cell culture supernatants, or fermentation broths. Vivaspin® Turbo 4 is suitable for initial sample volumes of 2–4mL and achieves its high flow rates due to the double vertical membranes which minimize protein polarization and subsequent fouling of the membrane. Additionally, the sleek internal profile ensures maximum process speeds right down to the last drops. The UV joining technology allows for a smooth joint transition between membrane and plastic housing, allowing complete sample recovery from the unique pipette friendly deadstop pocket. The dead stop pocket is an impermeable concentrate pocket integrally molded below the membrane surface, thereby eliminating the risk of filtration to dryness.
For samples up to 15mL, see the Vivaspin® Turbo 15.
