Technologies pertaining to a centrifuge that comprises a vector-seeking linkage are disclosed herein. In a general embodiment, the centrifuge comprises a spindle that is rotatable about an axis of rotation. The centrifuge also has an arm that is coupled to the spindle, and a vector-seeking linkage that is coupled to the arm. The vector-seeking linkage provides two rotational degrees of freedom with respect to a load coupled to the vector-seeking linkage. The centrifuge is well-suited for a variety of applications, including sensor testing, solution separation, and producing accelerations expected to be experienced during flight.
