Sample processing systems and methods of using those systems for processing sample materials located in sample processing devices are disclosed. The sample processing systems include a rotating base plate on which the sample processing devices are located during operation of the systems. The systems also include a cover and compression structure designed to force a sample processing device towards the base plate. The preferred result is that the sample processing device is forced into contact with a thermal structure on the base plate. The systems and methods of the present invention may include one or more of the following features to enhance thermal coupling between the thermal structure and the sample processing device: a shaped transfer surface, magnetic compression structure, and floating or resiliently mounted thermal structure. The methods may preferably involve deformation of a portion of a sample processing device to conform to a shaped transfer surface.
