A new DNP polarizer device suitable for laboratory or small animal imaging applications is be presented. In order to facilitate construction and operation of such a system, a greatly simplified design is introduced here permitting polarization of up to four samples for rapid sequential dissolution with less than 10 min latency in-between. Basic design criteria and performance measurements are presented.
