Vivapure®Mini Ion Exchange spin columns are centrifugal devices, based on Sartobind Membrane Adsorber technology as their chromatography matrix. The devices are ready-to-use and cannot run dry by their design. For many protein purification applications, they can replace time-consuming column chromatography. The rapid 1-2-3 bind-wash-elute protocol especially lends itself to screening applications, where many samples are processed parallel. Vivapure®Mini is available with three different membrane chemistries and with medium (1 mg/unit) or high (4 mg/unit) protein binding capacity. Vivapure®Mini units are intended for use in swing-out rotors and accommodate 0.5 ml and 0.4 ml samples, respectively.
