  • Heating, shaking, and magnetizing apparatus and method of operating the same
    Patent number: 8984968
    Abstract: An apparatus for processing a liquid sample in a sample tube. The apparatus includes a base, a receptacle for receiving a sample tube, and a heating portion coupled to the base to selectively apply heat to the receptacle. A shaking portion is coupled to the base and supports the receptacle. The shaking portion agitates the receptacle with respect to the base. A magnetizing portion is coupled to the base and movable to selectively change a magnetic field with respect to the receptacle.
