tion or buffer exchange application with Highest flow rates are achieved due to their double verticle membranes which minimize protein polarization and subsequent fouling of the membrane. Additionally, their sleek internal profile ensures maximum process speeds right down to the last 150 µl.The UV joining technology allows for a smooth joint housing, allowing complete sample recovery from the unique pipette friendly deadstop pocket. The dead stop pocket (patent pend- ing) is an impermeable concentrate pocket surface, thereby eliminating the risk of filtra- The Vivaspin® Turbo 15 devices are the opti- mal solution for protein concentration from dilute samples e.g. after chromatography, cell culture supernatants or fermentation Operation
Vivaspin® Turbo 15 concentrators can be used in swing bucket or fixed angle rotors accepting standard conical bottom tubes. In a single spin, solutions can be concentrated up to 150 +. Samples are typically concen- Equipment Required
